Note The S5U1C62xxxD system requires a host computer with a RAM capacity of about 140K bytes.

Since the ICE (S5U1C62000H) is connected to the host computer with a RS-232C serial interface,

adapter board for asynchronous communication will be required depending on the host computer

used.

3 DEVELOPMENT FLOW

Figure 3.1 shows the development flow through the S5U1C62xxxD.

Concerning file names

All the input-output file name for the each development support tool commonly use "C2XXYYY". In

principle each file should be produced in this manner. Seiko Epson will designate the "YYY" for each

customer.

4 INSTALLATION

The S5U1C62xxxD tools are included on the CD-ROM of the S5U1C62000A (S1C60/ 62 Family Assembler

Package), and they can be installed in your hard disk using the installer (Setup.exe) on the CD-ROM.

Refer to the "S5U1C62000A Manual" for how to install the S5U1C62xxxD tools.

Note The DMS6200 configures a menu from files that are located in the current directory. Therefore, do

not move the development tools from the directory in which the DMS6200 exists.

To invoke an editor (DOS version) or other programs from the DMS6200, copy those executable

files to the directory in which the DMS6200 exists.

5 DIFFERENCES FROM MODEL TO

MODEL AND PRECAUTIONS

There may be some models in which the following two types software tools contained in the

S5U1C62xxxD are not included.

(1) Segment Option Generator SOG62XX

This is not included in the software tools of models in which the segment option has not been set.

(2) Melody Assembler MLA628X

This is not included in the software tools for the models (Other than S1C62N8X) that do not have the

melody function.

Please be aware of the following points in setting the host system.

(1) The S5U1C62xxxD system requires a host computer with a RAM capacity of about 140K bytes.

(2) Since the ICE is connected to the host computer with a RS-232C serial interface, adapter board for

asynchronous communication will be required depending on the host computer used.

(3) In order for the MDC62XX to handle numerous files, set the number of files described in the

CONFIG.SYS to 10 or more (e.g., FILES = 20).

1 DIFFERENCES DEPENDING

ON THE MODEL

The DMS6200 is a software tool that is common to the all models of the S1C62 Family and there is

no difference in operating procedure. However, the content of such things as the menu screen may vary

due to differences in the configuration of the software for each model and differences in the directory

content in the DMS6200.

The below two types that are included in the explanation and display screen examples may not be present

in certain models.

(1) The SOG62XX and C2XXYYYS.* are only available in models offering the segment option.

(2) The MLA628X, C28XYYY.M* and C28XYYYA.* are only available in models offering the melody

function.

When models that do not have the above functions are used, disregard the respective program names and

file names indicated in the manual.

Refer to the "S5U1C62xxxD Manual" for the software tools included in the S5U1C62xxxD.

2 DMS6200 OUTLINE

The DMS6200 (Development Tool Management System) is a software which selects the

S5U1C62xxxD software development support tool and the program such as an editor in menu form and

starts it.

In this way the various software frequently executed during debugging can be effectively activated.

CROSS ASSEMBLER ASM62XX

1 DIFFERENCES DEPENDING

ON THE MODEL

Since the memory capacity will vary with each model of the S1C62 Family you must pay attention

to the following points when preparing a program.

The limiting items for each model are indicated in the "S5U1C62xxxD Manual".

■ ROM area

The ROM capacity will vary depending on the model.

The number of banks (16 pages/ bank) and the number of pages (256 steps/ page) are determined by

this ROM capacity and the memory setting pseudo-instruction and the "PSET" instruction is limited to

within its range.

Valid specification range

ORG pseudo-instruction:

PAGE pseudo-instruction:

BANK pseudo-instruction:

0000H–ROM final step

00H–number of page - 1

1 bank configuration model → 0H only

2 bank configuration model → 0H and 1H

00H–number of page - 1

PSET instruction:

When a specification beyond this valid specification range is made to the ASM62XX an error is pro-

duced.

■ RAM area

The RAM capacity varies depending on the model.

The number of pages (256 words/ page) is determined according to the RAM capacity. Also, the

undefined area includes from the 0 address to the final RAM address.

When an undefined address is set in the index register, memory access to it becomes invalid, but be

careful that no errors develop in the ASM62XX.

■ Undefined code

In the S1C62 Family, the instruction set is not different from model to model. However, you may not be

able to use instructions such as the SLP instruction and those that access the page section (XP and YP)

of the index register depending on the RAM content.

CROSS ASSEMBLER ASM62XX

2 ASM62XX OUTLINE

2.1 Outline

The ASM62XX cross assembler (the ASM62XX in this manual) is an assembler program for generating the

machine code used by the S1C62XXX 4-bit, single-chip microcomputers. It can be used under PC-DOS.

The Cross Assembler ASM62XX will assemble the

program source files which have been input by the

user's editor and will generate an object file in Intel-

Hex format and assembly list file.

A>EDLIN C2XXYYY.DAT

Create the source file

In this assembler, program modularization has been

made possible through macro definition functions and

programming independent of the ROM page structure

has been made possible through the auto page set

function. In addition, consideration has also been given

to precise error checks for program capacity (ROM

capacity) overflows, undefined codes and the like, and

for debugging of such things as label tables for assem-

bly list files and cross reference table supplements.

2.2 ASM62XX Input/Output Files

ASM62XX reads a source file, assembles it, and outputs object files and an assembly listing file.

■ Source file (C2XXYYY.DAT)

This is a source program file produced using an editor such as EDLIN. The file name format is

C2XXYYY, and the file name must not exceed seven characters in length. Character string YYY should

be determined by referencing the device name specified by Seiko Epson. The file extension must be

added ".DAT".

■ Object file (C2XXYYYH.HEX, C2XXYYYL.HEX)

This is an assembled program file in Intel hex format. Because the machine code of the S1C62XXX is 12-

bit, the high-order bytes (bits 9 to 12 suffixed by high-order bits 0000B) are output to file

3 ASM62XX OPERATION PROCEDURE

This section explains how to operate ASM62XX.

3.1 Starting ASM62XX

When starting ASM62XX, enter the following at DOS command level (when a prompt such as A> is being

displayed):

_ indicates a blank.

A parameter enclosed by [ ]

can be omitted.

ASM62XX _ [drive-name:] source-file-name [.shp] _ [-N]

indicates the return key.

When starting ASM62XX through the DMS6200, selects the "ASM62XX.EXE" and source file in the menu

screen, and input options necessary.

■ Drive name

If the source file is not on the same disk as ASM62XX.EXE, specify a disk drive mounted the floppy disk

storing the source file before input the source file name. If the source file is on the same disk as

ASM62XX.EXE, it does not need to specify the disk drive.

■ Source file name

This is the name of the source file to be entered for ASM62XX. The source file name must not exceed

seven characters in length. File extension .DAT must not be entered.

■ .shp

Characters s, h, and p are options for specifying the file I/ O drives, and can be omitted.

s: Specifies the drive from which the source file is to be input. A character from A to P can be

specified. If @ is specified, the source file in the current drive (directory) is input. Even if a drive

name is prefixed to the source file name, this option is effective.

h: Specifies the drive to which the object file (HEX) is to be output. A character from A to P can be

specified. If @ is specified, the object file is output to the current drive (directory). If Z is

specified, only assembly is executed; the object file is not generated.

p: Specifies the drive to which the assembly listing file is to be output. A character from A to P can

be specified. If @ is specified, the object file is output to the current drive (directory). If X is

specified, a listing containing error messages is output to the console. If Z is specified, the

assembly listing file is not generated.

Characters s, h, p must all be specified; only one or two of them is not sufficient.

■ -N option

The code (FFH) in the undefined area of program memory is not created.

Note The program data to be provided does not use the "-N" option. The FFH data should be inserted into

the undefined program area.

3.2 Selecting Auto-Page-Set Function

After the start-up message, the following message is displayed, prompting the user to select the auto-page-

set function.

DO YOU NEED AUTO PAGE SET?(Y/N)

Press the "Y" key if selecting the auto-page-set function, or the "N" key if not selecting it. At this stage, the

user can also return to the DOS command level by entering "CTRL" + "C" key.

■ Auto-page-set function

When the program branches to another page through a branch instruction such as JP, the branch-

destination page must be set using the PSET instruction before executing the branch instruction.

The auto-page-set function automatically inserts this PSET instruction. It checks whether the branch

instruction page is the same as the branch-destination one. If the page is different, the function inserts

the "PSET" instruction. If the page is the same, the function performs no operation.

Therefore, do not select the auto-page-set function if "PSET" instructions have been correctly included

in the source file.

Note When auto-page-set is selected, there are restricted items related to source programming. See

"4.3.1 Label".

3.3 Generating a Cross-Reference Table

After the auto-page-set function has been selected, the following message is output, prompting the user to

select cross-reference table generation.

DO YOU NEED CROSS REFERENCE TABLE?(Y/N)

Press the "Y" key if generating the cross-reference table, or the "N" key if not generating it. At this stage,

the user can also return to DOS command level by entering "CTRL" + "C" key.

Note If the assembly listing file output destination (p option) is specified as Z (listing not generated) at the

start of ASM62XX, the above message is not output and the cross-reference table is not generated.

■ Cross-reference table

The cross-reference table lists the symbols and their locations in the source file, and is output at the end

of the assembly listing file in the following format:

CROSS REFERENCE TABLE PAGE X- 1

LABEL1 4#

LABEL2 15#

....

Symbol

Number of the program statement

(# indicates the number of the statement at which the symbol was defined)

This table should be referenced during debugging. An error such as duplicate definition of a symbol can

be easily detected.

CROSS ASSEMBLER ASM62XX

4 SOURCE FILE FORMAT

The source file contains the source program consisting of S1C62XXX instructions (mnemonics) and

pseudo-instructions, and is produced using an editor such as EDLIN.

Refer to the "S1C6200/ 6200A Core CPU Manual" and the "S1C6xxx Technical Manual (Software)" for

instruction sets.

4.1 Source File Name

A desired file name not exceeding seven characters in length can be assigned to each source file. The

format must be as follows:

C2XXYYY.DAT

"YYY" of the "C2XXYYY.DAT" is an alphanumeric character string of up to three characters, and should be

determined by referencing the device name specified by Seiko Epson. The file extension must be ".DAT".

4.2 Statements

Each source program statement must be written using the following format.

Basic format: <Index>[:]

Example:

EQU

ORG

100H

INIT

START:

;To init.

Label

field

Mnemonic

field

Operand

field

Comment

field

A statement consists of four fields: label, mnemonic, operand, and comment. Up to 132 characters can be

used for one statement. Fields must be delimited by one or more blanks or tabs.

The label and comment fields are optional. Blank lines consisting only of a carriage return (CR) code are

also allowed.

Although each statement and field (excluding the label field) can begin at any desired column. The

program becomes easier to understand if the heads of corresponding fields are aligned.

4.2.1 Label field

The label field can contain a label for referencing the memory address, a symbol that defines a constant, or

a macro name. This field can be omitted if the statement name is not required. The label field must begin

at column 1 and satisfy the following conditions.

• The length must not exceed 14 characters.

• The same name as a mnemonic or register name must not be used.

• The following alphanumeric characters can be used, but the first character must not be a digit:

A to Z, a to z, 0 to 9, _ , ?

• The uppercase and lowercase forms of a letter are equivalent.

• ??nnnn (n is a digit) cannot be used as a name.

A colon ":" can be used as a delimiter between a label field and the mnemonic field. If a colon is used,

neither blanks nor tabs need to be written subsequently.

Statements consisting of only a label field are also allowed.

III-6

EPSON

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

CROSS ASSEMBLER ASM62XX

4.2.2 Mnemonic field

The mnemonic field is used for an instruction mnemonic or a pseudo-instruction.

4.2.3 Operand field

The operand field is used for the operands of the instruction. The form of each operand and the number of

operands depend on the kind of instruction. The form of expressions specifying values must be one of the

following:

• A numeric constant, a character constant, or a symbol that defines a constant

• A label indicating a memory address

• An operational expression for obtaining the specified value

If the operand consists of two or more expressions, the expressions must be separated by commas ",".

4.2.4 Comment field

The comment field is used for comment data such as program headers and descriptions of processing. The

contents of this field do not affect assembly or the object files generated by assembly.

The part of the statement from a semicolon ";" to the CR code at the end of the statement is considered to be

the comment field. Statements consisting of only a comment field are also allowed. When a comment

spans multiple lines, a semicolon must be written at the beginning of each line.

4.3 Index

ASM62XX allows values to be referenced by their indexes.

Refer to Section 4.2.1, "Label field", for the restrictions on index descriptions.

4.3.1 Label

A label is an index for referencing a location in the program, and can be used as an operand that specifies a

memory address as immediate data in an instruction. For example, a label can be used as the operand of

an instruction such as JP by writing the label in the branch-destination statement.

The name written in the label field of an EQU or SET instruction is considered to be a symbol, not a label.

Example:

JP NZ,LABEL1

LABEL1: LD A,0

A label can be assigned to any statement, but the label assigned to the following pseudo-instructions is

ignored:

ORG, BANK, PAGE, SECTION, END, LABEL, ENDM

Note When selecting the auto-page-set function (see Section 3.2), a statement consisting of only a label

must be written immediately before the JP or CALL instructions.

Example:

PGSET:

JP LABEL

DEVELOPMENT TOOL REFERENCE MANUAL

EPSON

III-7

CROSS ASSEMBLER ASM62XX

4.3.2 Symbol

A symbol is an index that indicates a numeric or character constant, and must be defined before its value is

referenced (usually at the beginning of the program). The defined symbol can be used as the operand that

specifies immediate data in an instruction.

Example:

ON EQU 1

OFF EQU 0

(See Section 4.5 for EQU.)

LD A,ON

; = LD A,1

; = LD A,0

LD A,OFF

4.4 Constant and Operational Expression

This section explains the immediate data description formats.

4.4.1 Numeric constant

A numeric constant is processed as a 13-bit value by ASM62XX. If a numeric constant greater than 13 bits

is written, bit 13 and subsequent high-order bits are ignored.

Note that the number of actual significant bits depends on the operand of each instruction. If the value of a

constant is greater than the value that can be accommodated by the actual number of significant digits, an

error occurs.

Example:

ABC EQU 0FFFFH

LD A,65535

→

ABC is defined as 1FFFH.

An error occurs because it exceeds the significant digit

count (4 bits).

The default radix is decimal. The radix description formats are as follows:

Binary numeral:

Octal numeral:

Decimal numeral:

A numeral suffixed with B, such as 1010B (=10) or 01100100B (=100).

A numeral suffixed with O or Q, such as 012O (=10) or 144Q (=100).

A numeral alone or a numeral suffixed with D, such as 10 or 100D (=100).

Hexadecimal numeral: A numeral suffixed with H, such as 0AH (=10) or 64H (=100).

If the value begins with a letter from A to F, it must be prefixed with 0 to distinguish

it from a name.

4.4.2 Character constant

A character constant is one or two ASCII characters enclosed by apostrophes (' '). A single ASCII character

is processed as eight-bit data. If two or more ASCII characters are written, only the last two characters are

significant as 13-bit data.

Examples:

'A'(=41H), 'BC'(=0243H), 'PQ'(=1051H), 'DEFGH'→ 'GH'(=0748H; DEF is ignored.)

The apostrophe itself cannot be processed as a character constant, so it must be written as a numeric

constant, such as 27H or 39.

EPSON

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

CROSS ASSEMBLER ASM62XX

4.4.3 Operator

When specifying a value for an item such as an operand, an operational expression can be written instead

of a constant, and its result can be used as the value.

Labels and symbols as well as constants can be used as terms in expressions. These values are processed as

13-bit data (bit 14 and subsequent high-order bits are ignored); the operation result also consists of 13 bits.

If the result exceeds the number of significant digits of the instruction operand, an error occurs.

There are three types of operator—arithmetic, logical, and relational—as listed below (a and b represent

terms, and _ represents one or more blanks).

■ Arithmetic operators

There are 11 arithmetic operators including the ones for addition, subtraction, multiplication, division,

bit shifting, and bit separation.

Monadic positive (indicates the subsequent value is positive)

Monadic negative (indicates the subsequent value is negative)

Addition (unsigned)

-a

a+b

a-b

Subtraction (unsigned)

a*b

Multiplication (unsigned)

a/b

Division (unsigned)

a_MOD_b

a_SHL_b

Remainder of a/ b

Shifts a b bits to the left. ←[b7<<<<<<b1]←0

Example: 00000011B SHL 2 → 00001100B

a_SHR_b

HIGH_a

LOW_a

Shifts a b bits to the right. 0→[b7>>>>>>b0]→

Example: 11000011B SHR 2 → 00110000B

Separates the high-order eight bits from a (13 bits).

Example: HIGH 1234H → 12H

Separates the low-order eight bits from a (13 bits).

Example: LOW 1234H → 34H

■ Logical operators

There are four logical operators as listed below. The logical operator returns the result of logical

operation on the specified terms.

a_AND_b

a_OR_b

a_XOR_b

NOT_a

Logical product

Example: 00001111B AND 00000011B → 00000011B

Logical sum

Example: 00001111B OR 11110000B → 11111111B

Exclusive logical sum

Example: 00001111B XOR 00000011B → 00001100B

Logical negation

Example: NOT 00001111B → 11110000B

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

EPSON

III-9

CROSS ASSEMBLER ASM62XX

■ Relational operators

A logical operator compares two terms; if the relationship between the terms is as the operator

specifies, 1FFFH (true) is returned; if not, 0 (false) is returned.

a_EQ_b

a_NE_b

a_LT_b

a_LE_b

a_GT_b

a_GE_b

True when a is equal to b

True when a is not equal to b

True when a is less than b

True when a is less than or equal to b

True when a is greater than b

True when a is greater than or equal to b

Be sure to insert one or more blanks for symbol "_" between terms. All operators must be entered in

uppercase letters.

An expression can contain one or more operators and pairs of parenthesis. In this case, operators are

basically evaluated from left to right. However, an operation stipulated by an operator with higher priority

or by parentheses is executed earlier. Every left parenthesis must have a corresponding right parenthesis.

The following table shows the priority of operators.

4.4.4 Location counter

The start address of each instruction code is set in the location counter when a statement is assembled. A

label or $ can be used when referencing the location counter value in a program.

■ Location counter

The location counter consists of 13 bits: one bit for the bank field, four bits for the page counter field,

and eight bits for the step counter field.

Bank

Page counter

Step counter

Bit

Contents Bank

Page address

PCP

Step address

PCS

BNK

Example:

Location counter

(BNK) (PCP) (PCS)

1 02

JP $+3

The location counter indicates the start address of the JP instruction, and the PCS value (02) is assigned to $.

Consequently, the statement is assembled as "JP 5", and the program sequence jumps to the location three

steps before (PCS=05) when it is executed.

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

CROSS ASSEMBLER ASM62XX

4.5 Pseudo-Instructions

There are four types of pseudo-instruction: data definition, memory setting, assembler control, and macro.

These pseudo-instructions as well as operational expressions can be used to govern assembly, and are not

executed in the developed program.

In the subsequent explanations, the items enclosed by < > in the pseudo-instruction format must be written

in the statement (do not write the < > characters themselves). Symbol _ represents one or more blanks or

tabs. One or more symbols and constants or an operational expression can be used in <expression>. See

Section 4.6 for macro functions.

4.5.1 Data definition pseudo-instructions

There are three data definition pseudo-instructions: EQU, SET, and DW. The EQU and SET pseudo-

instructions each define a symbol, and the DW pseudo-instruction presets data in program memory.

■ EQU (Equate)

To define a symbol

The EQU pseudo-instruction defines <symbol> (written in the label field) as having the value of

<expression> (written in the operand field).

If a value greater than 13 bits is specified in <expression>, bit 14 and subsequent high-order bits are

ignored.

This definition must be made before the symbol is referenced in the program. A U-error occurs if an

attempt is made to reference a symbol that has not been defined.

The same symbol cannot be defined more than once. A P-error occurs if an attempt is made to define a

symbol that has already been defined.

Examples:

ZERO EQU

30H

ONE

EQU

ZERO+1

31H

← P-error because ONE has been defined more than twice

FOUR EQU

TWO*2

← U-error because TWO has not been defined

■ SET

To define a symbol

Like EQU, the SET pseudo-instruction defines the value of <symbol> as being <expression>. The SET

pseudo-instruction allows a symbol to be redefined.

Examples:

ZERO EQU

30H

BIT

SET

← Redefinition possible

SET

BIT SHL 1← Previously-defined items can be referenced

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

EPSON

III-11

CROSS ASSEMBLER ASM62XX

■ DW (Define Word)

To preset data

The DW pseudo-instruction assigns the value of <expression> (the low-order 12 bits when the value is

greater than 12 bits) to the current memory location, indicated by the location counter.

Examples:

Location counter

(BNK) (PCP) (PCS)

2 0A

2 0B

2 0C

TABLE DW 141H ; = RETD 'A'

DW 142H ; = RETD 'B'

DW 143H ; = RETD 'C'

<label> can be omitted.

4.5.2 Memory setting pseudo-instructions

The program memory mounted at the S1C62XXX is divided into 256-step pages. Memory management

(including the setting of the program location and page boundaries) during program generation must be

controlled by the source program.

The memory setting pseudo-instructions are used to specify memory management. The assembler sets the

location counter according to these pseudo-instructions.

If a memory area that has already been used is specified or a statement that exceeds the page is used

without specifying that the statement is to exceed the page, the assembler displays an exclamation mark "!",

indicating a warning, and ignores all subsequent statements until the next correct statement. This should

be taken into account.

When using the auto-page-set function, the space for insertion of the "PSET" pseudo-instruction must be

allocated in each page.

■ ORG (Origin)

ORG_<Expression>

To set the location counter

The ORG pseudo-instruction sets the location counter to the value of <expression>.

If the ORG pseudo-instruction is not written at the beginning of the program, the location counter is set

to 0 (BNK=0, PCP=0, PCS=0) and assembly is started.

The ORG pseudo-instruction can be used at multiple locations in the program. However, it cannot be

used to set the location to a value before the current location. If this is attempted, an exclamation mark

"!", indicating a warning, is displayed, and all subsequent statements until the next correct statement are

ignored.

A label can be written before the ORG statement, but it cannot be referenced because it is not cataloged

in the label table. In this case, write the label in the statement following the ORG pseudo-instruction.

Example:

ORG 0100H ; BNK=0, PCP=1, PCS=00H

START

An R-error occurs if a value is specified exceeding the ROM capacity.

Note The upper limit of program memory depends on the model. (Refer to the "S5U1C62xxxD

Manual".)

III-12

EPSON

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

CROSS ASSEMBLER ASM62XX

■ BANK

BANK_<Expression>

To set the bank (BNK)

The BANK pseudo-instruction sets the value of <expression> in the bank (BNK) field, and sets the page

counter (PCP) and step counter (PCS) to 00H.

The BANK pseudo-instruction can be written at multiple locations in the program. However, it cannot

be used to specify the current bank (excluding the specification in page 00, step 00) or a previous bank.

If it is used to specify the current bank or a previous bank, an exclamation mark "!", indicating a

warning, is displayed, and all subsequent statements until the next correct statement are ignored.

A label can be written before the BANK statement, but it cannot be referenced because it is not

cataloged in the label table. In this case, write the label in the statement after the BANK pseudo-

instruction.

■ PAGE

PAGE_<Expression>

To set the page counter (PCP)

The PAGE pseudo-instruction sets the value of <expression> in the page counter (PCP) and sets the

step counter (PCS) to 00H.

The PAGE pseudo-instruction can be written at multiple locations in the program. However, it cannot

be used to specify the current page (excluding the specification in step 00) or a previous page. If it is

used to specify the current page or a previous page, an exclamation mark "!", indicating a warning, is

displayed, and all subsequent statements until the next correct statement are ignored.

A label can be written before the PAGE statement, but it cannot be referenced because it is not

cataloged in the label table. In this case, write the label in the statement after the PAGE pseudo-

instruction.

Example:

Location counter

(BNK) (PCP) (PCS)

4.5.3 Assembler control pseudo-instructions

■ END

END

To terminate assembly

The END statement terminates assembly. All statements following the END statement are ignored. Be

sure to write this statement at the end of the program. If it is missing, assembly may not terminate.

A label can be written before the END statement, but it cannot be referenced because it is not cataloged

in the label table.

4.6 Macro-Functions

When using the same statement block at multiple locations in a program, the statement block can be called

using a name defined beforehand. A statement block that has been so defined is called a macro.

Unlike a subroutine, the statement block is expanded at all locations where it is called, so the programmer

should consider the statement block size and frequency of use and determine whether a macro or a subrou-

tine is more appropriate.

4.6.2 Macro-definitions

The macro-definition should be done by using the MACRO and the ENDM instructions (pseudo-instruc-

tion).

■ MACRO ~ ENDM

<Macro-name>_MACRO_[<Dummy-argument>, ...]

Statement

ENDM

The statement block enclosed by a MACRO pseudo-instruction and an ENDM pseudo-instruction is

defined as a macro. Any name can be assigned to the macro as long as it conforms to the rules regard-

ing the characters, length, and label field.

A macro can have an argument passed to it when it is called. In this case, any symbol can be used as a

dummy argument in the macro definition where the actual argument is to be substituted and the same

symbol must be written after the MACRO pseudo-instruction. Multiple dummy arguments must be

separated by commas (,).

Be sure to write the ENDM statement at the end of a macro-definition.

Example: This macro loads data from the memory location specified by ADDR into the A or B register specified

by REG. Sample call: LDM A,10H

LDM MACRO REG,ADDR

X,ADDR

REG,MX

ENDM

These dummy arguments are replaced by actual arguments when the macro is expanded.

■ LOCAL

If a macro having a label is expanded at multiple locations, the label duplicates, causing an error. The

LOCAL pseudo-instruction prevents this error occurring.

LOCAL_<Label-name>[,<Label-name>...]

The label specified by the LOCAL pseudo-instruction is replaced by "??nnnn" when the macro is

expanded. Field nnnn is a four-digit decimal field, to which values 0001 to 9999 are assigned

sequentially.

The LOCAL pseudo-instruction must be written at the beginning of the macro. The LOCAL pseudo-

instruction is ignored if another instruction precedes it.

Example:

WAIT MACRO CNT

LOCAL LOOP

LOOP SBC

A,CNT

A,1

NZ,LOOP

←

Replaces LOOP with ??nnnn at expansion.

ENDM

4.6.3 Macro-calls

The defined macro-name can be called from any location in the program by using the following format:

[<Label>]_<Macro-name>_ [<Actual-argument>, ...]

The MACRO can be called by using the macro-name.

When arguments are required, write actual arguments corresponding to the dummy arguments used in the

macro-definition. Multiple actual arguments must be separated by commas (,).

Actual and dummy arguments correspond sequentially from left to right. If the number of actual argu-

ments is greater than the number of dummy arguments, the excess actual arguments are ignored. If the

number of actual arguments is less than the number of dummy arguments, the excess dummy arguments

are replaced by nulls (00H).

Any label can be written before the macro-name.

5 ERROR MESSAGES

If an error occurs during assembly, ASM62XX outputs the appropriate error symbol or error

message listed below to the console and assembly listing file.

Only a single error symbol is output at the beginning (column 1) of the statement that caused the error. (If

two or more errors occurred, only the error with highest priority is output.)

The following error symbols are listed in order of priority, starting with the one with the highest priority.

S (Syntax Error) ............................................. An unrecoverable syntax error was encountered.

U (Undefined Error) ...................................... The label or symbol of the operand has not been defined.

M (Missing Label) .......................................... The label field has been omitted.

O (Operand Error) ......................................... A syntax error was encountered in the operand, or the operand

could not be evaluated.

P (Phase Error) ............................................... The same label or symbol was defined more than once.

R (Range Error) .............................................. • The location counter value exceeded the upper limit of the

program memory, or a location exceeding the upper limit was

specified.

• A value greater than that which the number of significant

digits of the operand will accommodate was specified.

! (Warning) ..................................................... • Memory areas overlapped because of a "PAGE" or "ORG"

pseudo-instruction or both.

• A statement exceeded a page boundary although its location

was not specified.

FILE NAME ERROR................................. The source file name was longer than 8 characters.

FILE NOT PRESENT................................ The specified source file was not found.

DIRECTORY FULL ................................... No space was left in the directory of the specified disk.

FATAL DISK WRITE ERROR............... The file could not be written to the disk.

1 DIFFERENCES DEPENDING ON THE MODEL

The MLA628X is not included in the software tools for models (other than the S1C62N8X) that do

not have the melody function.

The melody ROM capacity varies depending on the model in models (S1C62N8X) having the melody

function. You should be aware that the number of melody data and their bit structure will vary, as a result.

The limiting items for each model are indicated in the "S5U1C62N8xD Manual".

2 MLA628X OUTLINE

2.1 Outline and Execution Flow

The Melody Assembler MLA628X is an assembler that

outputs melody ROM data of the 4-bit single-chip micro-

A>EDLIN C28XYYY.MDT

Create the source file

computers S1C628XX Series. MLA628X assembles the

C28XYYY

source file which has been input by the user's editor and

outputs the object file in Intel-HEX format as well as the

assembly list file and document file.

Source file

2.2 MLA628X Input/Output Files

MLA628X inputs the source file, and after assembly it outputs the melody HEX file, assembly list file and

document file.

■ Source file (C28XYYY.MDT)

This is a source program file of the melody data. Generate the source file using an editor such as

EDLIN while referencing the Chapter 3.

■ Melody HEX file (C28XYYYA.HEX)

This is a melody data file (Intel hexa format) used for the evaluation board (S5U1C62N8xE). One

melody ROM is generated by writing this file with the ROM writer.

Also, this file can be loaded into the evaluation board through the ICE by using the OPTLD command.

Note: Set all unused ROM areas to FFH when writing the HEX file into EPROM.

When loaded with ICE, the file format is checked, and an error results when it outside the specifiable

range is specified. Refer to the "S5U1C62N8xD Manual" for the restrictions of each models.

■ Melody assembly list file (C28XYYY.MPR)

Melody ROM list file with melody ROM data and error messages (if any) added to each line of the

source file. The scale ROM table can be created at the end of the file.

■ Melody document file (C28XYYYA.DOC)

This is a data file used to generate the mask patterns. Combine the completed document file with the

program files and option document files using the mask data checker MDC628X, and submit to Seiko

Epson.

3 STARTING MLA628X

To starting MLA628X, enter the following at the DOS command level (when a prompt such as A> is

being displayed):

_ indicates a blank.

A parameter enclosed by [ ]

can be omitted.

MLA628X_[drive name:]source filename[.shp]_[-H]

indicates the return key.

When starting MLA628X through the DMS6200, selects the "MLA628X.EXE" and source file in the menu

screen, and input options necessary.

■ Drive name

When the source file is in a different drive from MLA628X.MDT, the drive name is input before the

source filename. If in the same drive, then it may be omitted.

■ Source filename

The source file to input to MLA628X.

Note Make the source filename up to seven characters long, and do not input the extension (".MDT").

■ .shp

Characters s, h, and p are options specifying the file's input/ output drive, as explained below. These

may be omitted, and input is valid for both upper- and lower-case.

s: Specifies the drive from A through P that inputs the source file.

When "@" is specified, the source file on the current drive (directory) is input.

The "s" specification is valid when the drive name is input before the source filename.

h: Specifies the drive from A through P that outputs the melody HEX file and melody document file.

When "@" is specified, output is made to the current drive (directory).

When "Z" is specified, only assembly is performed and the melody HEX file and melody document

file are not created.

p: Specifies the drive from A through P that outputs the assembly list file.

When "@" is specified, output is made to the current drive (directory).

When "X" is specified the list including error messages is output from the console.

When "Z" is specified, the assembly list file is not created.

Specify s, h and p at the same time. These cannot be specified separately.

■ -H option

"-H" is the option to indicate activation of the conversion program from the melody document file to the

melody HEX file.

When this option is specified, the [shp] option is disabled. The melody document file of the current

drive is input and the melody HEX file is created for the current drive. Input can be in upper- and

lower-case.

4 FORMAT OF SOURCE FILE

Contents of the source file, created with an editor such as EDLIN, are configured from the

S1C628XX melody codes and the pseudo-instructions described later.

4.1 Source File Name

The source file can be named with a maximum of any seven characters. As a rule, keep to the following

format.

C28XYYY.MDT

Three alphanumerics are entered in the "YYY" part. Refer to the model name from Seiko Epson. The

extension must be ".MDT".

4.2 Statement (line)

Write each of the source file statements (lines) as follows:

Basic format: <Attack>

<Note>

<Scale>

<; comment>

Example:

.TEMPC0=5

.TEMPC1=8

.OCTAVE=32

;

A4#

;1st Melody

Attack field

Note field

Scale field

End bit field Comment field

The statement is made up of the five fields: attack field, note field, scale field, end bit field, and comment

field. Up to 80 characters can be written in the statement. The fields are separated by one or more spaces

or by inserting tabs.

The end bit fields and comment fields can be filled in on an as-needed basis.

A blank line is also permitted for the CR (carriage return) code only. However, it is not permitted on the

last line. Each of the fields can be started from any column.

(1) Attack field

Control of the attack output is written.

When "1" is written, attack output is performed. When "0" is written, attack output is not performed.

(2) Note field

Table 4.2.1 Notes and corresponding codes

No.

Eight notes can be specified with the 3 bits

melody data. Fill in the note field with

numbers from 1 to 8.

Note

Table 4.2.2 Rests and corresponding codes

No.

When the "RR" (rest) is described in scale

field, the rest may be selected from among 8

types as shown in Table 4.2.2.

DEVELOPMENT TOOL REFERENCE MANUAL

MELODY ASSEMBLER MLA628X

(3) Scale field

The scale field can be filled in with any scale (C3 through C6#).

When inputting the scale data directly, prefix the data with "$". In this case, the input data range is 00H

through FDH.

Moreover, the rest may be selected by describes "RR" in the scale field.

The number of specifiable scales varies depending on the model.

(Refer to the "S5U1C62N8xD Manual".)

(4) End bit field

The instruction indicating the end of the melody is written in the end bit field. When "1" is written, the

melody finishes with the melody data of that address. Otherwise, write "0", or omit it altogether.

(5) Comment field

Any comment, such as the program index or processing details, can be written in the comment field,

with no affect on the object file created with the assembler.

The comment field is the area between the semicolon ";" and the CR code at the end of the line.

A line can be made up of a comment field alone. However, if the comment extends into two or more

lines, each line must be headed with a semicolon.

5 PSEUDO-INSTRUCTIONS

The pseudo-instruction is for the assembler, and cannot be executed by the melody data after

development.

In the explanations below, the symbols "<" and ">" used in the pseudo-instruction format indicate the

contents of the statement. These symbols are not actually written. "_" indicates one or more spaces or tabs.

The symbol, constant, arithmetic expression and so forth is written in "<expression>".

5.1 Address-Setting Pseudo-Instruction

■ ORG (ORIGIN)

ORG_<Expression>

Sets location counter

The ORG instruction sets the value of <expression> in the location counter.

If the ORG instruction does not head the source file, the location counter is set to 0 and assembly is

performed. The ORG instruction can be used in multiple places in the program. However, it cannot be

set in a location ahead of the current location counter, otherwise all the statements will be invalid until

the next correct setting is performed, and "!" (Warning) is displayed.

When a value exceeding the ROM capacity is specified, an R error results.

5.2 Option-Setting Pseudo-Instructions

■ Tempo selection

The 2 types of tempo may be selected from

among 16 types by using the option-setting

pseudo-instructions (".TEMPC0 = n") and

(".TEMPC1 = n").

The option-setting pseudo-instructions and

the corresponding tempo generated are

shown in Table 5.2.1.

The 2 types of tempo for TEMPC0 and

TEMPC1 are selected by specifying n.

The proper use of the 2 types of tempo

selected is specified through the software.

The 2 types of tempo which may selected

are: TEMPC0 to be played when "0" is

written on the TEMPC register (address:

F2H, data bit: D1) and the TEMPC1 to be

played when "1" is written on the said

This setting cannot be omitted.

IV-6

EPSON

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

MELODY ASSEMBLER MLA628X

■ .TEMPC1

.TEMPC1 = n

Sets TEMPC1 (n = 0–15)

The TEMPC1 option is set by specifying n as an integer in the range 0 to 15.

This setting cannot be omitted.

■ .OCTAVE

.OCTAVE = m

Sets scale range (m = 32 or 64)

Decides the scale range by selecting the specification of the melody multiplier circuit.

The specification becomes 32 kHz for m = 32, and the range becomes (C3–C6#).

The specification becomes 64 kHz for m = 64, enabling output of notes one octave higher (C4–C7#) than

can be done with the 32 kHz specification.

For instance, even if the scale in the source file is C5, the actual sound generated will be C6.

This setting cannot be omitted.

6 ERROR MESSAGES

When errors occur during assembly, MLA628X outputs the following error symbols or error

messages to the console and assembly list file.

Just one error symbol is output at the head (first column) of the statement that generated an error. (When

multiple errors have been generated, the symbol for the error of highest priority is output.)

The following error symbols are shown in order from highest priority.

■ Error symbol (errors that can be assembled)

• S (Syntax error)................................. Major syntax error.

Error in scale field ......... Exceeded scale range: C3–C6#

Error in note field .......... Exceeded note range: 1–8

Error in attack field ....... Number other than 0 or 1 was input.

Error in end bit field ...... Number other than 0 or 1 was input.

• O (Scale ROM overflow) ................. The definition exceeded the scale ROM capacity.

• R (Range error) ............................. The value of the location counter exceeded the upper limit of the

melody ROM capacity. Otherwise, the specified location exceeded

the upper limit.

■ Error messages

(Fatal errors preventing assembly or output of assembly results)

• OPTION COMMAND MISSING .... Options cannot be set.

• FILE NAME ERROR ..................... The source filename has eight or more characters.

• FILE NOT PRESENT .................... The specified source file is not there.

• DIRECTORY FULL ....................... No more room in the directory of the specified disk.

• FATAL DISK WRITE ERROR ....... The file cannot be written to the disk.

1 DIFFERENCES DEPENDING ON THE MODEL

The set option content will vary depending on the model.

Here only the operation will be explained, so you should refer to the "S5U1C62xxxD Manual" concerning

the option specifications and the selection screen.

2 FOG62XX OUTLINE

2.1 Outline of Function Option Generator

With the 4-bit single-chip S1C62XXX microcomputers, the customer may select hardware options. By

modifying the mask patterns of the S1C62XXX according to the selected options, the system can be custom-

ized to meet the specifications of the target system.

Option list

generation

The FOG62XX Option Generator (hereinafter called

FOG62XX) is a software tool for generating data files used

to generate mask patterns. It enables the customer to

Start FOG62XX

interactively select and specify pertinent items for each

hardware option. From the data file created with FOG62XX,

the S1C62XXX mask pattern is automatically generated by a

general purpose computer.

Set function

option

The HEX file for the evaluation board (S5U1C62xxxE)

hardware option ROM is simultaneously generated with the

data file. By writing the contents of the HEX file into the

EPROM and mounting it on the evaluation board, option

functions can be executed on the evaluation board.

Figure 2.1.1 shows the FOG62XX execution flow.

Fig. 2.1.1 FOG62XX execution flow

2.2 FOG62XX Input/Output Files

Function options can be interactively selected, so an input file need not be generated. Select the hardware

options that meet the specifications of the target system and record them in the option list (paper for

recording items in preparation for input operation; explained later).

FOG62XX outputs the following data files:

• Function option document file (C2XXYYYF.DOC)

This is a data file used to generate the mask patterns for such items as I/ O ports. This file must be sent

with the completed program file. Already selected options can be modified.

• Function option HEX file (C2XXYYYF.HEX)

This is a function option file (Intel hexa format) used for evaluation board. One evaluation board

function option ROM is generated by writing this file with the ROM writer.

Remarks:

1 DIFFERENCES DEPENDING

ON THE MODEL

The segment output specific, display memory capacity and address will vary depending on the

model.

Here the explanation will focus on the method of operation. For the optional specifications, we will provide

an outline explanation as an example for the case of models with standard segment specifications that are

set by the four terminal common output, so you should refer to the "S5U1C62xxxD Manual" for details on

each model.

The SOG62XX is not included in the software for models that are not set by the segment option.

2 SOG62XX OUTLINE

2.1 Outline and Execution Flow

With the 4-bit single-chip S1C62XXX microcomputers, the customer may select the LCD segment options.

By modifying the mask patterns of the S1C62XXX according to the selected options, the system can be

customized to meet the specifications of the target system.

The SOG62XX Segment Option Generator (hereinafter called SOG62XX) is a software tool for generating

data files used to generate mask patterns. From the data file created with SOG62XX, the S1C62XXX mask

pattern is automatically generated by a general purpose computer.

The HEX file for the evaluation board

2.2 SOG62XX Input/Output Files

SOG62XX reads a source file containing segment port specification, and output following files.

■ Segment option source file (C2XXYYY.SEG)

The specifications of segment ports must be set in the segment source file (input file for SOG62XX). If

the segment source file is not generated, SOG62XX stops execution.

Generate the segment source file using an editor such as EDLIN while referencing the option list.

■ Segment option document file (C2XXYYYS.DOC)

This is a data file used to generate the mask patterns of the segment decoder and segment output port.

■ Segment option HEX file (C2XXYYYS.HEX)

This is a segment option file for evaluation board (Intel hexa format). Evaluation board segment option

ROMs are generated by writing this file with the ROM writer.

Remarks:

• File name "YYY" is specified for each customer by Seiko Epson.

• Combine the segment option document file (C2XXYYYS.DOC) with the program files (C2XXYYYH.HEX

and C2XXYYYL.HEX) and the function option document file (C2XXYYYF.DOC) using the mask data

checker (MDC62XX): copy the combined file into another diskette and submit to Seiko Epson.

• Set all unused ROM areas to FFH when writing the HEX file into the EPROM. (Refer to "S5U1C62xxxE

Manual" for the ROM installation location.)

L: Low order address

D: Data bit

Create a segment option source file by

using the option list as reference.

3.2 Segment Ports Output Specifications

For the output specification of the segment output ports (SEG0–SEG*), segment output and DC output can

be selected in units of two terminals. When used for liquid crystal panel drives, select segment output;

when used as regular output port, select DC output. When DC output is selected, either complementary

output or Pch open drain (Nch open drain is set depending on the model used) may further be selected.

However, for segment output ports that will not be used, select segment output.

■ When segment output is selected

The segment output port has a segment decoder built-in, and the data bit of the optional address in the

segment memory area can be allocated to the optional segment.

The segment memory may be allocated only one segment and multiple setting is not possible.

Segment allocation is set to H for high address, to L for low address (0–F), and to D for data bit (0–3)

and are recorded in their respective column in the option list. For segment ports that will not be used,

write a hyphen ("-") each on the H, L, and D columns.

The allocated segment displays when the bit for this segment memory is set to "1", and goes out when

bit is set to "0".

■ When DC output is selected

The DC output can be selected in units of two terminals. Also, either complementary output or open

drain output is likewise selected in units of two terminals. When the bit for the selected segment

memory is set to "1", the segment output port goes high (VDD), and goes low (VSS) when set to "0".

Segment allocation is the same as when segment output is selected but for the while the segment

memory allocated to COM1–COM3 becomes ineffective. Write three hyphens ("---") in the COM1–

COM3 columns in the option list.

Note The configuration of the common terminals (COM0–COM3) may vary depending on the model.

SEGMENT OPTION GENERATOR SOG62XX

SOG62XX OPERATION PROCEDURE

4.1 Creating Segment Option Source File

The SOG62XX needs, as an input file, a segment option source file containing the specifications for the

segment output ports. Using the editor, generate this source file by referencing the contents of the option

list. Use the following file name. For "YYY", enter the string distributed by Seiko Epson.

C2XXYYY.SEG

Write the output specifications (SEG output, DC complementary output, or DC open drain output) and the

segment memory-SEG ports correspondence data (data that associates segment memory addresses to SEG

ports) in the file. Comments may also be written in the file. The description procedure is explained by

using a sample segment option source file.

Note In the following examples, there are cases of models where the common output is 4 terminals and

the 900H–AFFH is set in the display memory area. You should be aware of the fact that the number

of output ports and the display memory address may vary depending on the model.

• Each SEG port number corresponds to an actual device, so it must be unique. Moreorve, data descrip-

tions in accordance with the following format are required for segments SEG0–SEG25.

• Off areas COM0 to COM3, write three successive "---" (3 hyphens) as data for unused areas. SEG port

numbers are needed even if the ports themselves will not be used, so write "---" (3 hyphens) for all areas

COM0 to COM3.

Example: When not using COM2 in SEG8

8_981_980_---_A22

Example: When not using SEG12

12_---_---_---_---

• When "DC output" is selected, write the segment memory-SEG ports correspondence data for COM0;

"---" (hyphens) for COM1 to COM3.

Example: When outputting SEG20 and SEG21 as DC output

20_933_---_---_---

21_A33_---_---_---

• Symbol "_" indicates a blank or tab. Be sure to write one or more blanks or a tab between the SEG port

number, COM0, COM1, COM2, and COM3.

■ Output specification selection data

This data is used to specify whether the SEG port will be used as a segment output port, a DC comple-

mentary output port, or a DC open drain output port.

Write data after inserting one or more blanks or a tab after the segment memory-SEG ports correspond-

ence data.

S: Segment output

C: DC complementary output

P: DC Pch open drain output

Either one is set, depending on the model.

N: DC Nch open drain output

• The SEG port output specifications must be selected in units of two ports, so write the selection data

carefully while referencing the option list.

Example: When outputting SEG22 and SEG23 as DC complementary output

22_AE0_---_---_---_C

23_AF0_---_---_---_C

• Select "SEG output" for the segment ports that will not be used.

Example: When not using SEG18

18_---_---_---_---_S

Note Only complementary output is enabled as the DC output of the SEG ports of evaluation board.

Therefore, complementary output is enabled even if open drain output is selected. Respond to it by

adding external circuits as required.

1 DIFFERENCES DEPENDING

ON THE MODEL

The S5U1C62xxxE has the same functions as the actual IC (S1C62XXX). Although the method of

operation and other functions are the same, the terminal layout of the I/ O and LCD connectors and the

input/ output signal specifications are different. The layout in the top panel is also different.

Refer to the "S5U1C62xxxE Manual" included with the hardware for details on each model.

2 S5U1C62XXXE OUTLINE

The S5U1C62xxxE is a debugging tool for the S1C62XXX, with various functions such as single step

and program break.

Almost the same functions that the S1C62XXX CPU has can be implemented by writing application

program and option data created by the option generator into EPROM, and installing it in the

S5U1C62xxxE.

Debugging and CPU monitoring can be done using the S5U1C62xxxE operation switches and LED indica-

tors; therefore, debugging is possible with the S5U1C62xxxE alone.

In addition, the S5U1C62xxxE can interface with the ICE (S5U1C62000H) in-circuit emulator, and so

perform a higher level of debugging.

3 PRECAUTIONS

Take the following precautions when using the S5U1C62xxxE:

3.1 Precautions for Operation

• Turn the power of all equipment off before connecting or disconnecting cables.

• To turn the POWER switch of the S5U1C62xxxE off, then on again, wait for at least 10 seconds after

turning off before turning on.

• When ROMs are inserted into the L and H ROM sockets, lock the lever securely by positioning it

horizontally. After the ROMs have been removed from the sockets, lock the lever at the same position

above. If the lever is left upright, poor contact may result.

• Confirm that the ROMs have been installed correctly, then operate the S5U1C62xxxE.

• If the S5U1C62xxxE does not operate normally, perform the operation test. (See "S5U1C62xxxE

Manual".)

3.2 Differences from Actual IC

There are some differences in functions between the S5U1C62xxxE and the actual IC.

■ I/O differences

The response time has been changed by the differences in logic level (5 V for the S5U1C62xxxE), output

drive capability, and pull-down/ up resistance. When creating key scan routines, especially, pay

attention to the response time.

■ LCD differences

• The LCD contrast is adjusted by the VADJ control. However, the contrast level of each actual IC is

fixed, so it cannot be adjusted.

• No Pch/ Nch open drain option can be selected.

• The output drive capability is different.

■ Power-on sequence differences

The S5U1C62xxxE performs configuration and determines the internal state when the power is

switched on. Then, it works as the IC does. Therefore, the I/ O state of the S5U1C62xxxE is unstable

until configuration has completed. This affects the power-on reset time.

■ Function differences

The oscillation start and stop times are different from those of the IC.

Because the logic level of S5U1C62xxxE is higher than it of actual IC.

Functions may differ depending on the model, so you should refer to the "S5U1C62xxxE Manual" for other

differences.

4 NAMES AND FUNCTIONS OF PARTS

This section describes the names and functions of the parts of the S5U1C62xxxE.

4.1 Basic Functions

The S5U1C62xxxE has the following basic functions:

■ Program execution (Run function)

Install the EPROM containing the application program and execute the program.

■ Single-step program operation (Single-step function)

Programs may be run instruction by instruction to check the internal state of the CPU as it changes with

each instruction.

■ Program execution suspension at a given address (Break function)

A breakpoint may be set at an address at which it is desired to suspend program execution. After

execution has stopped at the breakpoint, it can be restarted with the program run function.

■ Displaying program addresses and instruction codes during a break

Program addresses and instruction codes may be displayed on the LED indicators.

■ Displaying the contents of RAM, registers, and flags during a break

The contents of RAM, the A, B, X, and Y registers, the stack pointers, and the flags may be displayed on

the LED indicators during a break.

■ Interface with ICE

The S5U1C62xxxE can interface with the ICE so that a higher level debugging environment may be

established.

■ Setting hardware options by installing function option and segment option ROMs

Hardware options, i.e., I/ O ports and segments, can be specified by writing option data for the func-

tions created by the function option generator and the segment option created by the segment option

generator into EPROM, and installing the EPROM.

EVALUATION BOARD S5U1C62XXXE

• BREAK POINT switches (BB, BP, BS)

These switches set a breakpoint address at which program execution stops. BB, BP, and BS are switches

that set the bank, page, and step, respectively, of the breakpoint address. When a switch is in the upper

position, it represents "1"; when it is in the lower position, it represents "0".

The breakpoint address set with the BREAK POINT switches is valid when the EN/ DIS switch is in the

EN position. When the set address matches the current address of the program being executed, the

program breaks, i.e., it stops immediately before executing the instruction at the current address. This

function does not work when the EN/ DIS switch is in the DIS position.

• RAM ADDRESS switches (SA)

These switches are used to set RAM addresses and to check the contents of RAM after a program break.

When a switch is in the upper position, it represents "1"; when it is in the lower position, it represents

"0". The contents of the address set with these switches are displayed on the RAM display LEDs.

• RUN key

This key restarts the program after a break. When it is pressed, the program continues, starting with the

instruction at the break address.

• STEP key

When this key is pressed, the program breaks immediately. If the key is pressed during a break, the

instruction step at the break address is executed, and the program breaks again. Thus, the program can

be executed step by step.

■ LEDs

The internal state of the CPU is indicated by the LEDs. An LED lit indicates "1"; an LED not lit indicates "0".

• RAM (3210)

The contents of the RAM address, which are fixed by the RAM ADDRESS switch,

are displayed.

• IR (BA9876543210) The instruction at the current address is displayed. If the program has stopped at

a breakpoint, the instruction is displayed before execution.

• PCP (3210)

• PCS (76543210)

• SP (76543210)

The value of the stack pointer is displayed.

• X (BA9876543210) The contents of the X index register are displayed.

• Y (BA9876543210) The contents of the Y index register are displayed.

• F/IF

The state of the interrupt flag is displayed.

The state of the decimal flag is displayed.

The state of the zero flag is displayed.

The state of the carry flag is displayed.

The contents of the A register are displayed.

The contents of the B register are displayed.

• F/DF

• F/ZF

and when it is connected to the ICE. Connection method, refer to Chapter 5, "CABLE CONNECTION".

Check the S5U1C62xxxE operation by mounting the supplied diagnostic ROMs as instructed in the

"S5U1C62xxxE Manual". It is recommended that this test be performed periodically.

Before doing the following, be sure to turn the POWER switch of the S5U1C62xxxE off.

6.1.1 Creation of target system

Mount the LCD panel, keys, and switches on the board to build a target system. Use the I/ O connectors

and LCD connectors supplied with the S5U1C62xxxE to connect the S5U1C62xxxE to the target system.

(For the pin layout of each connector, see the "S5U1C62xxxE Manual".)

Note: There is some difference in specifications between the S5U1C62xxxE and the actual CPU. Refer to

Section 2.2 in the "S5U1C62xxxE Manual", "Differences from Actual IC" when building a target

system.

6.1.2 Creation and installation of ROMs

Create the program ROMs, function option

Program ROMs (two)

ROM and segment option ROMs, and insert

them into the sockets of the S5U1C62xxxE.

When the S5U1C62xxxE is delivered, the

function option ROM and segment option

ROMs for a diagnostic program are already

installed. Replace them with the created

ROMs.

Segment option ROMs

(two, behind the

bottom cover, S.HEX)

(one, behined the top

cover, F.HEX)

Fig. 6.1.2.1 Installation of ROMs

• Program ROMs (two)

The program ROMs contain the application program machine code. Write the HEX files output by the

ASM62XX cross-assembler into EPROMs to create program ROMs. Since two HEX files containing the

high-order section (C2XXYYYH.HEX) and the low-order section (C2XXYYYL.HEX) of the machine code

are output, two ROMs are created. Insert H.HEX into socket H and L.HEX into socket L on the top

panel. These ROMs are not necessary when connecting the S5U1C62xxxE to the ICE.

• Function option ROM (one)

The function option ROM is used to specify function options, such as I/ O ports. Create the option ROM

from the function option HEX file (C2XXYYYF.HEX) output by the function option generator, and

insert it into the ROM1 socket (F.HEX) in the top cover.

• Segment option ROMs (two)

...Only for the models that have the segment option.

The segment option ROMs are used to specify segment output ports. Create two segment ROMs (with

the same contents) from the segment option HEX file (C2XXYYYS.HEX) output by the segment option

generator, and insert them into two S.HEX sockets in the bottom cover.

• EPROM specifications

Use EPROMs with the following specifications:

Program ROM:

Function option ROM: 27C64 to 27C512

Segment option ROM: 27C64 to 27C512

27C64 to 27C512

(250 ns or less access time)

(170 ns or less access time)

6.2 Independent Use of S5U1C62xxxE

This section describes operation when using the S5U1C62xxxE by itself.

The S5U1C62xxxE may be used independently by connecting a power supply to it. Use a 5 V DC regulator

(more than 3 A) as an external power supply. Connect it with the correct polarity (+ and -).

(Refer to Section 5.2, "Power Cable Connection".)

6.2.1 Power on/off

Before turning the POWER switch of the S5U1C62xxxE on, confirm the following:

(1) The power cable is connected correctly.

(2) The target system is connected correctly.

(3) The ROMs have been installed correctly.

After confirming the above items, turn the POWER switch of the S5U1C62xxxE on using the following proce-

dure:

(1) Turn the regulator on. If the regulator is of the variable-voltage type, set the output voltage to 5 V.

(2) Turn the POWER switch of the S5U1C62xxxE on.

Note: To turn the POWER switch of the S5U1C62xxxE off, then on, turn it off, wait for 10 seconds or more,

and then turn it on.

After the POWER switch of the S5U1C62xxxE has been turned on, the DONE LED (green) on the top cover

lights after several seconds to indicate that debugging may proceed. If the DONE LED is still off 10 seconds

or more after the POWER switch has been turned on, do the following:

(1) Turn the POWER switch of the S5U1C62xxxE off.

(2) Confirm that the ROMs have been installed properly, and the cables connected properly.

(3) Check the fuse.

(4) Turn the POWER switch of the S5U1C62xxxE on.

If the DONE LED still does not light, do a self-diagnosis.

For the self-diagnosis method, refer to the "S5U1C62xxxE Manual".

6.2.2 Debugging

When the S5U1C62xxxE is used alone, it provides the following debugging functions. The method of

operation is given below.

• Program free run

When the RESET switch (on the top cover) is pressed, the S5U1C62xxxE enters the program run state,

and executes the application program from page 1, step 0. Before pressing the RESET switch after the

power to the S5U1C62xxxE has been switched on, make sure that the DONE LED is lit.

• Program break

The program may be stopped at the address set by the BREAK POINT switches. This function is valid

when the EN/ DIS switch is in the EN position. The program stops at the program address where the

breakpoint is set. It stops before the instruction at the breakpoint is executed. The program may be

stopped by pressing the STEP key.

When the program is stopped, the LED indicators for the internal state of the CPU show the current

state. So debug by checking this state against the program.

To restart the program after a break, set the next breakpoint, and press the RUN key.

The single-step operation (described below) can be performed by pressing the STEP key instead of the

RUN key.

S1C62 FAMILY

DEVELOPMENT TOOL REFERENCE MANUAL

EPSON

VII-9

EVALUATION BOARD S5U1C62XXXE

• Single step

By pressing the STEP key after a program break, the one instruction at the current address can be

executed, and the program stopped at the next address (program break). Using this function, the

program run state can be confirmed.

For the other functions, refer to the "S5U1C62xxxE Manual".

6.3 Operation When ICE (S5U1C62000H) is Connected

This section explains the operation and use of the S5U1C62xxxE when it is connected to the ICE.

Set up the S5U1C62xxxE as follows when it is connected to the ICE:

(1) Do not connect the power supply.

(2) Keep on turning the POWER switch off.

(3) Set all the switches on the operation panel to their lower positions.

6.3.1 Power on/off

Power to the S5U1C62xxxE is supplied by the ICE, and the power is switched on and off by pressing the

POWER switch of the ICE. Keep the POWER switch of the S5U1C62xxxE off.

Note: To turn the POWER switch of the ICE off, then on, turn it off, wait for 10 seconds or more, and then

turn it on.

After the POWER switch of the ICE has been turned on, the DONE LED (green) on the top cover of the

S5U1C62xxxE lights after several seconds to indicate that debugging may proceed. If the DONE LED is still

off 10 seconds or more after the POWER switch has been turned on, do the following:

(1) Turn the POWER switch of the ICE off.

(2) Confirm that the circuit breaker of the ICE is on.

(3) Confirm that the ROMs have been installed properly and the cables connected properly.

(4) Turn the POWER switch of the ICE on.

If the DONE LED still does not light, do a self-diagnosis.

For the self-diagnosis method, refer to the "S5U1C62xxxE Manual".

6.3.2 Debugging

Debugging is done with the host computer, and the S5U1C62xxxE is controlled by the ICE. For the method

of operation, refer to Part VIII, "ICE Control Software ICS62XX".

The switches except the reset switch and LEDs are invalid. Do not operate the switches of the S5U1C62xxxE

side. The target program ROM is invalid when the ROM is installed.

7 OPERATING TEST

Self-diagnosis of the S5U1C62xxxE can be performed with the following operating tests. To perform

these tests, the function option ROM, two segment ROMs and two program ROMs (supplied) are required.

If these ROMs have not been installed, insert them into the sockets. To use the S5U1C62xxxE

independently, connect the external power supply (5 V DC, 3 A).

Refer to the "S5U1C62xxxE Manual" for details of the operating test.

commands.

History control portion

Emulation consists of executing

and terminating functions of the

Target monitor portion

Break control portion

To the evaluation board

evaluation boardCPU and is

ICE firmware

controlled via the emulation

ROM sockets (H, L)

control portion. The evaluation

board CPU is halted unless the

Fig. 2.3.1.1 Block diagram of ICE functions

run (G command) or single step

(T command) operations are

invoked. In this condition the

emulation lamp on the ICE display is OFF and the HALT lamp is ON to indicate the set-up mode. Thus, the

A command, etc., are executed during the set-up mode.

The emulation program memory is set-up by instructions which activate the evaluation board CPU.

In the set-up mode, such operations as loading from the ROM sockets by the ICE control processor and

program setting by the host processor are executed.

Similarly, the evaluation board CPU data RAM is allocated to the emulation data memory.

The history control portion records the execution bus cycles of the evaluation board CPU and consists of a

8192 word × 88 bit memory. The large memory capacity allows evaluation board CPU register values to be

recorded in real time. The history is written in target run mode, and is analyzed by the ICE control

processor in the set-up mode.

The break control portion has the functions which check the evaluation board CPU bus condition whether

it is at a break point or not, and will stop the execution at the break point. Breaking at CPU register values

is also possible in real time. The ICE control processor monitors the evaluation board CPU on the target

monitor during target run mode. Results are displayed as on-the-fly information.

2.3.2 Break mode and break function

Breaks are supported in many modes.

(1) Break enable mode:

Makes the break function valid. Actions during break are decided according to the mode setting of

break-trace/ stop.

(2) Break disable mode:

Makes the break function invalid. ICE SYNC pin pulse output mode which does not terminate the G

command when in break condition. This function can be used as an oscilloscope synchronous signal to

measure the target circuit timing using the pulse as a reference.

(3) Break trace mode:

Temporarily stops the target run during break condition, and quickly restarts the program after

displaying the CPU register and execution time. Effective for viewing the program operation timing,

but not in true real time.

(4) Break stop mode:

A mode to break programs when they are consistent with break conditions.

Different types of breaks are described below.

(1) Reset switch:

Need not be in break mode to break. Used to reset the ICE; does not display the target register during

break.

(2) Break switch:

Need not be in break mode to break. evaluation board CPU register is properly displayed during break.

(3) ESC key:

Break induced by ESC key input from the host. Need not be in break mode to break. Evaluation board

CPU register is properly displayed during break.

(4) Break set command:

Break induced when CPU conditions and conditions set by BA, BD, BR or BM commands agree. Causes

a break in break enable mode and break stop mode, but does not cause break in break disable mode.

Cannot be set in break trace mode after completion of the instruction.

2.3.4 Display during run mode and during break

During run mode, the ICE control processor monitors the state of the evaluation board CPU. Monitored

data evaluation board CPU's executed program are displayed at intervals of about 500 msec when the on-

the-fly display mode is set (by the OTF command).

. . . Enter HALT mode, line feed, and HALT is displayed.

. . . HALT is canceled, operation is restarted, and PC is redisplayed.

Note HALT indicates execution of the HALT or SLP instruction.

When the printer is online and started, the PC values are printed in succession. PC is not displayed

during on-the-fly inhibit mode.

During a break, the cause of the break, post break PC (the next executed program address), the

contents of the CPU registers, and execution time are displayed.

*PC=xxxx

(1) There are three statuses possible after completing the emulation: BREAK HIT, ESC KEY, OR BREAK

SW. When a number of conditions prevail, only the highest priority position is displayed in the follow-

ing priority ranking: BREAK SW > ESC KEY > BREAK HIT. A break may also be initiated by the reset

switch; a reset switch break causes " *ICE6200 RESET SW TARGET*" to be displayed and

instructions are awaited. The register display and execution time display are not active in this mode.

(2) The displayed PC shows the next executed value. Register values following "A" indicate the values

during a break. In the above example, the values (indicated 2) results from completing to execute the

instruction of address 0200.

(3) Execution time mode and step number mode can be set during run time (using the #TIM command).

Millisecond is abbreviated to "mS". In step number mode, decimal values describe the run time, as in :

" *RUN TIME=501 STEPS".

When the execution time or step counters overflow, the message " *RUN TIME=TIMEOVER" is

displayed. For more details, see Section 2.3.10, "Measurement during command execution".

2.3.5 Break assigning commands

The ICE has a variety of break setting functions.

(1) Set break by PC:

Set by the BA command. The instruction is executed when the evaluation board CPU PC and the set

values agree, thus inducing a break. When the PSET command is entered at the set address, the PSET

and subsequent instruction are executed, then processing is halted. (When multiple PSET commands

are specified, the instructions are executed until a command other than PSET is encountered.)

Breaks can be set for multiple PC's (to the maximum capacity of program memory).

(2) Set break by RAM data:

Set by the BD command. A break is induced by the RAM data address, data, or R/ W AND condition.

Also, masks can be set for address, data and R/ W respectively.

When a break is induced by writing F data at address 10, the settings are: address=10, data=F, R/ W=W.

Any data can be used with the following settings: address=10, data=mask, R/ W=W. A break will occur

after execution of the memory access instruction which equals the set conditions. The break point can be

set to one point through these settings.

(3) Set break by register value:

Set by BR command. When the register values of the evaluation board CPU coincide with the set break

values, a break is initiated following execution of the instruction.

A break is induced by and AND condition set in the A, B, FI, FD, FZ, FC, X, or Y registers. Also, a mask

can be set in any of the registers. When a break is induced with register A=5, X=70, and Y=0A, the other

registers may be masked.

Example:

LD A,5

LD X,70

LD Y,0A . . . A break is induced when the above instruction is executed.

These settings will allow the operation to run in real time. The break point can be set at only one point.

Items (1), (2) and (3) above can be set independently.

When BA, BD and BR are set concurrently, a break will occur when any of the conditions coincide.

(4) Set compound break:

Set by BM command. A compound break occurs when breaks (1), (2) and (3) include AND statements.

Breaks can have the following elements masked: (coincide with PC), (coincide with RAM data address,

data, R/ W), (register value). The break point can be set at only one point. At the current setting, setting

(1) through (3) are automatically canceled. If settings (1) through (3) follow the current setting, the BM

condition is canceled.

Note Since the RAM data condition is a break element, the break will not be initiated without instructions

which access the RAM data.

ICE CONTROL SOFTWARE ICS62XX

2.3.6 Target interrupt and break

When a target interrupt occurs the moment of a break it is given priority over the break. The break is then

induced after the interrupt process is stacked. Next, the interrupt routine is executed from the top when the

run mode commences.

The PC displayed during a break is the top interrupt address.

When a break is set by the BR command with FI=1, the break and interrupt are generated simultaneously,

but due to the interrupt process, the register values after the break are:

*PC=0000 A=.... F=.DZC X=000 Y=010

FI reset

so as to reset the FI flag status.

2.3.7 History function

The evaluation board CPU information (PC, instruction code, RAM data address and data content, and

CPU internal registers) while running an emulation are fetched to the history memory region with each

CPU bus cycle. The history memory has a capacity of 8291 cycles, and can store 2730 (5 clock instructions

only) to 1365 (12 clock instructions only) new instructions executed by the evaluation board.

operation indicates the stack cycle.

Note * During interrupt processing, two HP are renewed. Otherwise, HP is renewed by the instruction

2.3.8 Break delay function

Users can refer to the programs until break by the history function mentioned in the previous section. In

the ICE this function has been expanded so that the history information before hitting the break condition

or before and after hitting break condition can be acquired and referred. To realize this function, this

system is designed not to terminate the program right after the hit of break condition, but to terminate the

program after acquiring specified history data. This specification is executed by the #HC command.

Note When specifying the break delay by using the break enable & break stop mode (see Section 2.3.2,

"Break mode and break function"), be sure that break is not made at the specified break condition.

2.3.9 Coverage function

ICE can acquire and indicate the address information of the program which was accessed during the

execution of the program. One can confirm which parts have completed troubleshooting and debugging by

referring to coverage information which is a result of executing programs for a long period of time. This

coverage function is specified by #CVD, and #CVR commands.

2.3.10 Measurement during command execution

The ICS62XX possesses a counting function which counts the time or the number of steps from starting the

target program to the occurrence of a break.

The counting range is described below.

(1) Time counting mode

6.5 µsec to 6.5 × 65535 µsec (=425.977 msec)

Measurement error : ±6.5 µsec

(The display is in millisecond units: msec)

Step 1 to step 65535

Measurement error : 0 steps

(error of 1 step may be presumed during interrupt process)

When the measurement range is exceeded, the following message is displayed:

*RUN TIME=TIMEOVER.

2.3.11 Self-diagnostic function

The ICE performs a self-check at power ON. When a check instruction (#CHK ) is input from the host

system, the self-test results are sent to the host.

#CHK

...System awaits instruction unless an error occurs.

A check instruction is automatically input when the ICS62XX system program is loaded.

B>ICS62XX

(Epson logo appears)

* ICE POWER ON RESET *

* DIAGNOSTIC TEST OK *

(Check instruction is automatically input; if no anomaly occurs, the

When the above display appears, it indicates that the ICE and host are connected properly and the ICE is

operating correctly.

If the ICE is power supply is OFF or the the cable to the host is not connected at the prompt, the following

message appears:

B>ICS62XX

*COMMUNICATION ERROR OR ICE NOT READY*

Then, when the ICE power supply is switched ON, a self-test is automatically performed and the following

message is displayed:

* ICE POWER ON RESET *

* DIAGNOSTIC TEST OK *

When an error message is displayed after entering the check instruction, it is likely to be due to hardware

failure. Contact customer support.

2.3.13 Limitations during emulation

When running emulations with the ICE and evaluation board connected, the evaluation board CPU is

normally stopped, as described in Section 2.3.1, "Operating features" (set up mode).

In the set up mode, the evaluation board CPU and peripherals are stopped, and inappropriate operations

cannot be initiated. Until the set up mode is canceled and the target program is executed, the evaluation

board CPU executes instructions provided by the command program of the ICE. The command program

continues to operate when the emulation is completed and returns to the set up mode.

Fig. 2.3.13.1 Evaluation board CPU operation

You should be aware that when the command program takes over, the timers and counters are enabled and

started from initial settings. Also, the watchdog timer is cleared immediately prior to the ICE switching to

emulation mode while under command program control.

Accordingly, the following points should be noted when using the ICE.

(1) When execution of the trace instruction (T,U) is prolonged

Evaluation board timer values can be renewed while the command program is operative.

(2) When the run is halted and restarted

The watchdog timer is cleared by the ICE before and after the emulation, thus the watchdog timer is not

continuous. The target program operates in real time when the run time is sufficiently long.

The command program runs approximately 30 steps before and after an emulation. When operating at 32

kHz clock speed, these steps require 6 msec + 6 msec = 12 msec. While at a clock speed of 455 kHz, the

command program steps before and after emulation require 400 µsec + 400 µsec = 800 µsec.

When the dump data command (#DD) is invoked, the I/ O area interrupt condition flag is read but not

cleared.

#DP

Function

The program area (emulation program memory) from <address 1> to <address 2> is displayed

in hexadecimal format.

(1) When <address 2> defaults, the contents of <address 1> are displayed in a single screen (21

lines, 21×8=168 addresses).

(2) When <address 1> and <address 2> default, a single screen is displayed from the previous

address plus one (one more than the previous address).

When DP alone is entered after power on, the data from address 0 are displayed.

(3) When more than one screen of data is displayed, a one line space appears between every

21 lines with about a one second pause.

(4) Hexadecimal and ASCII codes can be displayed together, but the ASCII data operands

are converted by the RETD and LBPX instructions before display.

Example:

Data content 142 ... ASCII display B

(Instruction: RETD 42)

(5) When the last program area passes, the operation terminates.

(6) Commands can be interrupted by input from the "ESC" key.

Function

Displays history data.

(1) Displays history data from <pointer 1> to <pointer 2>.

(2) When <pointer 2> defaults, displays history data of <pointer 1> in 21 lines.

(3) Numerals displayed in <pointer 1> and <pointer 2> are decimal, from 0 to 9999.

(4) The following contents are displayed for each instruction:

LOC:

PC:

IR:

OP:

OPR:

History pointer (decimal)

Program counter (hexadecimal)

Command code (hexadecimal)

Command mnemonic

When a break, "PC" is displayed.

Command operand

A,B,X,Y: Contents of A, B (Xp, Xh, Xl), (Yp, Yh, Yl) registers

IDZC:

Other:

Binary display of flag bit (1 when set, 0 when clear)

During execution of an instruction, the memory R/ W cycle and data are

displayed. Also, data interrupts INT1 (stack data) and INT2 are displayed

(5) History memory has a capacity of 8192 bus cycles. One the other hand, the S1C62 Family

has 5, 7 and 12 clock instructions. The 5 clock instructions require three bus cycles, 7 clock

instructions require four bus cycles, and 12 clock instructions require six bus cycles. Thus,

the final value of the history pointer is changed according to the executed instruction. The

maximum final value of the execution time for only a 5 clock instruction is approximately

2700, while the execution time for a 12 clock instruction is about 1300. When a break

occurs before the history memory reaches the end, the last value of the history pointer is

reduced.

(6) The history memory receives new data until a break occurs. Old data is erased when

number of executed GO commands exceeds 2700.

(7) The top of the history pointer is 0. When the last value of <pointer 2> is set, the values are

displayed to the last value.

(8) When there are no history data (Before GO command, after GO command execution,

during T command execution, or during HAR command execution), the following

message is displayed:

* NO HISTORY DATA *

(9) The HB command can be used to view history data immediately prior to a break.

#A,<address>

(With guidance)

Function

The mnemonic command is assembled and stored at the address indicated by <address>.

(1) Supports the mnemonics and operands in the instruction list used in the S1C62 Family.

(2) Operand expressions follow the configurations below:

r,q:

00 to 03 values

00 to FF values

00 to 0F values

A, B, MX or MY

In general, hexadecimal expressions do not have "H" appended at the end.

Three digit data can be input starting from the 0 column.

0FF input:

Validates FF

00FF input: Causes an error

An error is generated by invalidated values entered for p, s, l or i.

Only binary expressions (xxxxB) are allowed in the input area. The x in this case has a

fixed length of from one to four digits comprised either of 0 or 1, with "B" input last.

When less than three digits are input, the expression is handled as a binary expression or

an error.

(3) Either upper or lower case letters may be used for input.

(4) Mnemonic and operand codes should be separated by one or more character spaces or by

a tab code.

(5) An error is generated when an unsupported instruction is entered.

(6) A or B input gains register priority. Input 0A or 0B when entering immediate value

settings.

LD A,B

LD B,0A

Contents of B register are input to A register.

#BMR

Function

Sets the compound break function for multiple breaks when all conditions for the evaluation

board CPU PC, data RAM access, and register values coincide.

(1) Although the BA, BD and BR conditions can be set independently, the BM command

generates a break when all conditions for the PC, data RAM access, and register values

coincide. In other words, it can be thought of as the AND setting for the BA, BD and BR

commands.

(2) Previously set BA, BD and BR conditions are canceled by the BM command. Also, the BM

setting is canceled when the BA, BD and/ or BR conditions are set after the BM condition

is set.

(3) The BMR command cancels the BM condition.

(4) A break is set at only one point by the BM command. Each register setting can be masked.

Function

This instruction runs the target program. When a break condition is detected, program

execution is halted and the break status is displayed to complete the instruction.

■ Setting the Starting Address

(1) When an <address> is entered, the run starts from that address.

(2) With an R setting the evaluation board CPU is reset, and the run starts from the reset

address 0100.

(3) When the <address> and R setting are defaulted, the run starts from the current

address (PC which displays the status during the previous break).

When G is entered after power on, the run starts from address 0100, but the

evaluation board CPU is not reset.

Function

Executes trace, and single step actions of programs.

(1) The specified portion of the target program executes with a frequency indicated by the

<step number> from the specified <address> (65535 possible in decimal code). The PC,

instruction word and register contents are displayed with each execution.

(2) When the <step number> is defaulted, only one step is executed.

(3) When the <address> is defaulted, the specified number of steps is executed from the

current PC (PC at which the previous T command completed).

(4) When both <address> and <step number> are defaulted, only one step is executed from the

current PC. When this setting occurs after power on, one step is executed from PC=0100.

(5) When the <step number> is one (#T, <address> or #T), the instruction does not terminate

after one step, but a further step is executed by the "SP" key input, at which time the

instruction can be terminated by the "ESC" key input.

(6) In (1) above, the instruction is terminated by "ESC" key input.

*PC=01AC IR=xxx JP 10 A=x B=x X=xxx Y=xxx F=xxxx SP=013 ... "ESC"

Because the PSET command is used in relation to the subsequent instruction,

two command executions can be set by invoking the T command once.

*PC=01AD IR=xxx HALT _

Cursor

When the HALT command is executed by the T command, the command mnemonics are displayed

until the target interrupt as described above, but the register value is not displayed. When an interrupt

is properly input, the register is displayed and the next "SP" is awaited. The "SP" input restarts the

program after the interrupt routine.

When the target interrupt never occurs, the instruction can be forced to terminate by using the "ESC"

key. At that point, the HALT and T commands terminate, but the HALT command executes from the

next address when the T command is operative.

Notes

(1) The T command does not operate in real time. Therefore, the target timer is renewed. (For

details refer to Section 2.3.13, "Limitations during emulation".)

(2) When the H command is input after executing this command, the message, *NO HIS-

1 DIFFERENCES DEPENDING ON THE MODEL

Depending on the model, the MDC62XX input/ output file and the below two types of files in the

program that prepares the file may not be available.

(1) The SOG62XX and C2XXYYYS.DOC are only set in models that have the segment option.

(2) The MLA628X and C28XYYYA.DOC are only set in models that have the melody function.

When models that do not have the above functions are used, disregard the respectively below indicated

program names and data file names.

Refer to the "S5U1C62xxxD Manual" for the software tools included in the S5U1C62xxxD.

2 MDC62XX OUTLINE

2.1 Outline

The Mask Data Checker MDC62XX is a software tool which checks the program data (C2XXYYYH.HEX

and C2XXYYYL.HEX), option data (C2XXYYYF.DOC and C2XXYYYS.DOC), and melody data

(C28XYYYA.DOC) created by the user and creates the data file (C62XXYYY.PAn) for generating mask

patterns. The user must send the file generated through this software tool to Seiko Epson.

Moreover, MDC62XX has the capability to restore the generated data file (C62XXYYY.PA0) to the original

file format (C2XXYYYH.HEX, C2XXYYYL.HEX, C2XXYYYF.DOC, C2XXYYYS.DOC and C28XYYYA.DOC).
