1.2
Connecting the Emulator with the User System
To connect the E10A-USB emulator (hereinafter referred to as the emulator), the H-UDI port
connector must be installed on the user system to connect the user system interface cable. When
designing the user system, refer to the recommended circuit between the H-UDI port connector
and the MPU. In addition, read the E10A-USB emulator user's manual and hardware manual for
the related device.
Table 1.2 shows the type number of the emulator, the corresponding connector type, and the use of
AUD function.

Not available
The H-UDI port connector has the 36-pin and 14-pin types as described below. Use them
according to the purpose of the usage.
1. 36-pin type (with AUD function)
The AUD trace function is supported. A large amount of trace information can be acquired in
realtime. The window trace function is also supported for acquiring memory access in the
specified range (memory access address or memory access data) by tracing.
2. 14-pin type (without AUD function)
The AUD trace function cannot be used because only the H-UDI function is supported. For
tracing, only the internal trace function is supported. Since the 14-pin type connector is
smaller than the 36-pin type (1/2.5), the area where the connector is installed on the user
system can be reduced.

Recommended Circuit between the H-UDI Port Connector and the
MPU
1.5.1
Recommended Circuit (36-Pin Type)
Figure 1.3 shows a recommended circuit for connection between the H-UDI and AUD port
connectors (36 pins) and the MPU when the emulator is in use.
Notes: 1. Do not connect anything to the N.C. pins of the H-UDI port connector.
2. The /ASEMD0 pin must be 0 when the emulator is connected and 1 when the
emulator is not connected, respectively.
(1) When the emulator is used: /ASEMD0 = 0
(2) When the emulator is not used: /ASEMD0 = 1
Figure 1.3 shows an example of a circuit that allow the /ASEMD0 pin to be GND (0)
whenever the emulator is connected by using the user system interface cable.
When the /ASEMD0 pin is changed by switches, etc., ground pin 22. Do not connect
this pin to the /ASEMD0 pin.
3. When a network resistance is used for pull-up, it may be affected by a noise. Separate
TCK from other resistances.
4. The /CA signal in the user system is input to the /CA pin of the MPU. Connect this
signal to the H-UDI port connector as the output from the user system.
5. When the emulator is used, the /CA pin must be pulled up by a resistance of several
kilo-ohms whether the U-standby function is used or not.
6. The /TRST pin must be at the low level for a certain period when the power is
supplied whether the H-UDI is used or not. Reduce the power supplied to the /TRST
pin by pulling the pin up by a resistance of several kilo-ohms and setting HIZB8 = 0
in the HIZCRB register after a reset.
7. The pattern between the H-UDI port connector and the MPU must be as short as
possible. Do not connect the signal lines to other components on the board.
8. Since the H-UDI and the AUD of the MPU operate with the VccQH, supply only the
VccQH to the UVCC pin. Make the emulator’s switch settings so that the VccQH will
be supplied (SW2 = 1 and SW3 = 1) (as shown in figure 1.3).
9. The resistance values shown in the figure are recommended.
10. For the pin processing in cases where the emulator is not used, refer to the hardware
manual of the related MPU.
11. Either 3.0 V or 1.8 V can be selected as VccQ for the /CA pin or the /RESETP pin due
to the MPU specifications. These pins must be pulled up by the voltage level of VccQ.
In addition, when VccQ is selected as 1.8 V, VccQ is boosted because the lower limit
of the emulator’s UVCC or VccQH voltage is 2.5 V. However, it does not affect
MPU’s operation.

12. For the AUDCK pin, guard the pattern between the H-UDI port connector and the
MPU at GND level.

When the circuit is connected as shown in figure 1.3, the switches of the emulator are set as SW2
= 1 and SW3 = 1. For details, refer to section 3.8, Setting the DIP Switches, in the Debugger Part
of the SuperHTM Family E10A-USB Emulator User’s Manual.

1.5.2
Recommended Circuit (14-Pin Type)
Figure 1.4 shows a recommended circuit for connection between the H-UDI and AUD port
connectors (14 pins) and the MPU when the emulator is in use.
Notes: 1. Do not connect anything to the N.C. pins of the H-UDI port connector.
2. The /ASEMD0 pin must be 0 when the emulator is connected and 1 when the
emulator is not connected, respectively.
(1) When the emulator is used: /ASEMD0 = 0
(2) When the emulator is not used: /ASEMD0 = 1
Figure 1.4 shows an example of a circuit that allow the /ASEMD0 pin to be GND (0)
whenever the emulator is connected by using the user system interface cable.
When the /ASEMD0 pin is changed by switches, etc., ground pin 9. Do not connect
this pin to the /ASEMD0 pin.
3. When a network resistance is used for pull-up, it may be affected by a noise. Separate
TCK from other resistances.
4. The /CA signal in the user system is input to the /CA pin of the MPU. Connect this
signal to the H-UDI port connector as the output from the user system.
5. When the emulator is used, the /CA pin must be pulled up by a resistance of several
kilo-ohms whether the U-standby function is used or not.
6. The /TRST pin must be at the low level for a certain period when the power is

pin by pulling the pin up by a resistance of several kilo-ohms and setting HIZB8 = 0
in the HIZCRB register after a reset.
7. The pattern between the H-UDI port connector and the MPU must be as short as
possible. Do not connect the signal lines to other components on the board.
8. Since the H-UDI and the AUD of the MPU operate with the VccQH, supply only the
VccQH to the UVCC pin. Make the emulator’s switch settings so that the VccQH will
be supplied (SW2 = 1 and SW3 = 1) (as shown in figure 1.4).
9. The resistance values shown in the figures are recommended.
10. For the pin processing in cases where the emulator is not used, refer to the hardware
manual of the related MPU.
11. Either 3.0 V or 1.8 V can be selected as VccQ for the /CA pin or the /RESETP pin due
to the MPU specifications. These pins must be pulled up by the voltage level of VccQ.
In addition, when VccQ is selected as 1.8 V, VccQ is boosted because the lower limit

3. Low-Power States (Sleep, Software Standby, Module Standby, and U Standby)
For low-power consumption, the SH7339 has sleep, software standby, module standby, and U
standby states.
The sleep, software standby, and module standby states are switched using the SLEEP
instruction. When the emulator is used, only the sleep state can be cleared with either the
normal clearing function or with the [STOP] button, and a break will occur. For the U standby
state, refer to section 2.2.8, Notes on U Standby State.
Note: The memory must not be accessed or modified in sleep state.
4. Reset Signals
The SH7339 reset signals are only valid during emulation started with clicking the GO or
STEP-type button. If these signals are enabled on the user system in command input wait
state, they are not sent to the SH7339.
Note: Do not break the user program when the /RESETP, /BREQ, or /WAIT signal is being low.
A TIMEOUT error will occur. If the /BREQ or /WAIT signal is fixed to low during
break, a TIMEOUT error will occur at memory access.
5. Direct Memory Access Controller (DMAC)
The DMAC operates even when the emulator is used. When a data transfer request is
generated, the DMAC executes DMA transfer.
6. Memory Access during User Program Execution
When a memory is accessed from the memory window, etc. during user program execution,
the user program is resumed after it has stopped in the E10A-USB emulator to access the
memory. Therefore, realtime emulation cannot be performed.
The stopping time of the user program is as follows:
Environment:
Host computer: 800 MHz (Pentium® III)
SH7339: 60 MHz (CPU clock)
JTAG clock: 10 MHz (TCK clock)
When a one-byte memory is read from the command-line window, the stopping time will be
about 45 ms.
7. Memory Access during User Program Break
The emulator can download the program for the flash memory area (for details, refer to section
6.22, Download Function to the Flash Memory Area, in the Debugger Part of the SuperHTM
Family E10A-USB Emulator User’s Manual). Other memory write operations are enabled for
the RAM area. Therefore, an operation such as memory write or BREAKPOINT should be set
only for the RAM area.
12
Download from Www.Somanuals.com. All Manuals Search And Download.
8. Cache Operation during User Program Break
When cache is enabled, the emulator accesses the memory by the following methods:
•
•
At memory write: Writes through the cache, then writes to the memory.
At memory read: Does not change the cache write mode that has been set.
Therefore, when memory read or write is performed during user program break, the cache state
will be changed.

10. UBC
When [User] is specified in the [UBC mode] list box in the [Configuration] dialog box, the
UBC can be used in the user program.
Do not use the UBC in the user program as it is used by the emulator when [EML] is specified
in the [UBC mode] list box in the [Configuration] dialog box.
11. MFI Boot Mode
When the MFI boot mode is used, be sure to allocate the boot program from the top of
MFRAM.
12. Using RWDT
At power-on reset, the operation of RWDT is enabled. When RWDT is not used, be sure to
disable the operation of RWDT at the top of the user-reset program.

13. Memory Access during Break
In the enabled MMU, when a memory is accessed and a TLB error occurs during break, it can
be selected whether the TLB exception is controlled or the program jumps to the user
exception handler in [TLB Mode] in the [Configuration] dialog box. When [TLB miss
exception is enable] is selected, a “Communication Timeout error” will occur if the TLB
exception handler does not operate correctly. When [TLB miss exception is disable] is
selected, the program does not jump to the TLB exception handler even if a TLB exception
occurs. Therefore, if the TLB exception handler does not operate correctly, a “Communication
Timeout error” will not occur but the memory contents may not be correctly displayed.
14. Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be as follows:
•
When HS0005KCU01H or HS0005KCU02H is used: TCK = 0.625 MHz
15. [IO] window

The internal I/O registers can be accessed from the [IO] window. However, note the
following when accessing the SDMR register of the bus-state controller. Before accessing
the SDMR register, specify addresses to be accessed in the I/O-register definition file
(SH7339.IO) and then activate the HEW. After the I/O-register definition file is created,
the MPU’s specifications may be changed. If each I/O register in the I/O-register
definition file differs from addresses described in the hardware manual, change the I/O-
register definition file according to the description in the hardware manual. The I/O-
register definition file can be customized depending on its format. Note that, however, the
E10A emulator does not support the bit-field function.
Verify
In the [IO] window, the verify function of the input value is disabled.
16. Illegal Instructions
If illegal instructions are executed by STEP-type commands, the emulator cannot go to the
next program counter.

Notes: 1. When the [L-bus] or [I(M)-bus] radio button is selected, the bus cycles listed below
will be traced. The [I-bus] and [M-bus] radio buttons are only available when the
[I(M)-bus] radio button has been selected.
•
•
•
L-bus: A bus cycle on the L-bus generated by the CPU is acquired. A bus cycle is
also acquired when the cache has been hit.
I-bus: A bus cycle on the I-bus generated by the CPU or DMA is acquired. A bus
cycle is not acquired when the cache has been hit.
M-bus: A bus cycle on the M-bus generated by the CPU is acquired. A bus cycle is
not acquired when the cache has been hit.
It is not possible to acquire trace information on accesses to I-bus and M-bus at the
same time.
The address information acquired by the I-bus/M-bus is 28 bits and the upper 4 bits are
displayed as ‘*’. The source cannot be displayed in the [Trace] window.
21
Download from Www.Somanuals.com. All Manuals Search And Download.
When U-RAM or X/Y-RAM is accessed from the P0 space, the I-bus must be selected,
and when accessed from the P2 space, the L-bus must be selected. When a cache fill
cycle is acquired, I-bus must be selected.
2. Address setting when X/Y-bus is selected
To trace both the X/Y-bus when the X/Y-bus is accessed at the same time, the X-bus
condition must be set in channel A, and the Y-bus condition must be set in channel B.
(c) Software Trace Function
Note: This function can be supported with SHC/C++ compiler (manufactured by Renesas
Technology Corp.; including OEM and bundle products) V7.0 or later.
When a specific instruction is executed, the PC value at execution and the contents of one
general register are acquired by trace. Describe the Trace(x) function (x is a variable name) to
be compiled and linked beforehand. For details, refer to the SHC manual.
When the load module is downloaded on the target system and is executed while a software
trace function is valid, the PC value that has executed the Trace(x) function, the general
register value for x, and the source lines are displayed.
To activate the software trace function, select the [Software trace] check box in the [AUD
function] group box of the [Trace mode] page.
Notes on AUD Trace:
1. When the trace display is performed during user program execution, the mnemonics, operands,
or source is not displayed.
2. The AUD trace function outputs the differences between newly output branch source addresses
and previously output branch source addresses. The window trace function outputs the
differences between newly output addresses and previously output addresses. If the previous
branch source address is the same as the upper 16 bits, the lower 16 bits are output. If it
matches the upper 24 bits, the lower 8 bits are output. If it matches the upper 28 bits, the lower
4 bits are output.
The emulator regenerates the 32-bit address from these differences and displays it in the
[Trace] window. If the emulator cannot display the 32-bit address, it displays the difference
from the previously displayed 32-bit address.
3. If the 32-bit address cannot be displayed, the source line is not displayed.
4. In the emulator, when multiple loops are performed to reduce the number of AUD trace
displays, only the IP counts up.
5. In the emulator, the maximum number of trace displays is 65534 lines (32767 branches).
However, the maximum number of trace displays differs according to the AUD trace
information to be output. Therefore, the above pointers cannot be always acquired.
6. The AUD trace acquisition is not available when [User] is selected in the [UBC mode] list box
of the [Configuration] dialog box. In this case, close the [Trace] window.
22

7. Do not use the AUD full-trace mode for the VIO function.
8. If a completion-type exception occurs during exception branch acquisition, the next address to
the address in which an exception occurs is acquired.
Internal Trace Function: This function is activated by selecting the [Internal trace] radio button
in the [Trace type] group box of the [Trace mode] page. This function traces and displays the
branch instructions. The branch source address and branch destination address for the eight latest
branch instructions are displayed. See figure 2.1, [Trace mode] Page.
Notes: 1. If an interrupt is generated at the program execution start or end, including a step
operation, the emulator address may be acquired. In such a case, the following
message will be displayed. Ignore this address because it is not a user program
address.
*** EML ***
2. If a completion-type exception occurs during exception branch acquisition, the next
address to the address in which an exception occurs is acquired.
3. Trace information cannot be acquired for the following branch instructions:
•
•
The BF and BT instructions whose displacement value is 0
Branch to H'A0000000 by reset
4. The internal trace acquisition is not available when [User] is selected in the [UBC
mode] list box of the [Configuration] dialog box. In this case, close the [Trace]
window.
2.2.3
Notes on Using the JTAG (H-UDI) Clock (TCK) and AUD Clock (AUDCK)
1. Set the JTAG clock (TCK) frequency to lower than the frequency of the SH7339 peripheral
module clock (CKP).
2. Set the AUD clock (AUDCK) frequency to 50 MHz or lower. If the frequency is higher than
50 MHz, the emulator will not operate normally.
2.2.4
Notes on Setting the [Breakpoint] Dialog Box
1. When an odd address is set, the next lowest even address is used.
2. A BREAKPOINT is accomplished by replacing instructions of the specified address.
Accordingly, it can be set only to the internal RAM area. However, a BREAKPOINT cannot
be set to the following addresses:
•
•
•
•
An area other than CS0 to CS6 and the internal RAM
An instruction in which Break Condition 2 is satisfied
A slot instruction of a delayed branch instruction
An area that can be only read by MMU
3. During step operation, BREAKPOINTs are disabled.
23
Download from Www.Somanuals.com. All Manuals Search And Download.
4. Conditions set at Break Condition 2 are disabled when an instruction to which a
BREAKPOINT has been set is executed. Do not set a BREAKPOINT to an instruction in
which Break Condition 2 is satisfied.
5. When execution resumes from the address where a BREAKPOINT is specified, single-step
operation is performed at the address before execution resumes. Therefore, realtime operation
cannot be performed.
6. When a BREAKPOINT is set to the slot instruction of a delayed branch instruction, the PC
value becomes an illegal value. Accordingly, do not set a BREAKPOINT to the slot
instruction of a delayed branch instruction.
7. When a BREAKPOINT is set to the cacheable area, the cache block containing the
BREAKPOINT address is filled immediately before and after user program execution.
8. Note on DSP repeat loop:
A BREAKPOINT is equal to a branch instruction. In some DSP repeat loops, branch
instructions cannot be set. For these cases, do not set BREAKPOINTs. Refer to the hardware
manual for details.
9. When the [Normal] option is selected in the [Memory area] group box in the [General] page of
the [Configuration] dialog box, a BREAKPOINT is set to a physical address or a virtual
address according to the SH7339 MMU status during command input when the VPMAP_SET
command setting is disabled. The ASID value of the SH7339 PTEH register during command
input is used. When VPMAP_SET command setting is enabled, a BREAKPOINT is set to a
physical address into which address translation is made according to the VP_MAP table.
However, for addresses out of the range of the VP_MAP table, the address to which a
BREAKPOINT is set depends on the SH7339 MMU status during command input. Even
when the VP_MAP table is modified after BREAKPOINT setting, the address translated when
the BREAKPOINT is set valid.
10. When the [Physical] option is selected in the [Memory area] group box in the [General] page
of the [Configuration] dialog box, a BREAKPOINT is set to a physical address. A
BREAKPOINT is set after disabling the SH7339 MMU upon program execution. After
setting, the MMU is returned to the original state. When a break occurs at the corresponding
virtual address, the cause of termination displayed in the status bar and the [Output] window is
ILLEGAL INSTRUCTION, not BREAKPOINT.
11. When the [Virtual] option is selected in the [Memory area] group box in the [General] page of
the [Configuration] dialog box, a BREAKPOINT is set to a virtual address. A BREAKPOINT
is set after enabling the SH7339 MMU upon program execution. After setting, the MMU is
returned to the original state. When an ASID value is specified, the BREAKPOINT is set to
the virtual address corresponding to the ASID value. The emulator sets the BREAKPOINT
after rewriting the ASID value to the specified value, and returns the ASID value to its original
value after setting. When no ASID value is specified, the BREAKPOINT is set to a virtual
address corresponding to the ASID value at command input.
12. An address (physical address) to which a BREAKPOINT is set is determined when the
BREAKPOINT is set. Accordingly, even if the VP_MAP table is modified after
24
Download from Www.Somanuals.com. All Manuals Search And Download.
BREAKPOINT setting, the BREAKPOINT address remains unchanged. When a
BREAKPOINT is satisfied with the modified address in the VP_MAP table, the cause of
termination displayed in the status bar and the [Output] window is ILLEGAL INSTRUCTION,
not BREAKPOINT.
13. If an address of a BREAKPOINT cannot be correctly set in the ROM or flash memory area, a
mark z will be displayed in the [BP] area of the address on the [Source] or [Disassembly]
window by refreshing the [Memory] window, etc. after Go execution. However, no break will
occur at this address. When the program halts with the break condition, the mark z
disappears.
2.2.5
Notes on Setting the [Break Condition] Dialog Box and the BREAKCONDITION_
SET Command
1. When [Go to cursor], [Step In], [Step Over], or [Step Out] is selected, the settings of Break
Condition 2 are disabled.
2. Break Condition 2 is disabled when an instruction to which a BREAKPOINT has been set is
executed. Accordingly, do not set a BREAKPOINT to an instruction which satisfies Break
Condition 2.
3. When a Break Condition is satisfied, emulation may stop after two or more instructions have
been executed.
4. If a PC break address condition is set to the slot instruction after a delayed branch instruction,
user program execution cannot be terminated before the slot instruction execution; execution
stops before the branch destination instruction.
5. Break Condition 1,2 is used as the measurement range in the performance measurement
function when [PA-1 start point] and [PA-1 end point] are displayed on the [Action] part in the
[Break condition] sheet of the [Eventpoint] window. This applies when the Break Condition is
displayed with the BREAKCONDITION_DISPLAY command in the command-line function.
In this case, a break does not occur when Break Condition 1,2 is satisfied.
6. A break will not occur with the execution counts specified on the execution of the multi-step
instruction.
2.2.6
Note on Setting the UBC_MODE Command
In the [Configuration] dialog box, if [User] is set while the [UBC mode] list box has been set, the
STEP-type commands that use Break Condition 2 for implementation cannot be used.

Counted for accessing the cacheable area.
Cache-on counting
Accessing the non-cacheable area is counted less than the actual
number of cycles and counts. Accessing the cacheable, X/Y-RAM,
and U-RAM areas is counted more than the actual number of cycles
and counts.
Branch count
The counter value is incremented by 2. This means that two cycles
are valid for one branch.
Notes: 1. In the non realtime trace mode of the AUD trace, normal counting cannot be performed
because the generation state of the stall or the execution cycle is changed.
2. Since the clock source of the counter is the CPU clock, counting also stops when the
clock halts in the sleep mode.
2. Displaying the measured result
The measured result is displayed in the [Performance Analysis] window or the
PERFORMANCE_ANALYSIS command with hexadecimal (32 bits).
Note: If a performance counter overflows as a result of measurement, “********” will be
displayed.

Notes on U Standby State
Controlling Vcc (main) in the U standby state clears settings for peripheral modules in the SH7339
in which the emulator uses for debugging. Thus the appropriate function must be selected in the
[Recovery Information] page of the [Configuration] dialog box so that debugging can be
continued after returning to the U standby state.
Note: When using the U standby state, be sure to connect the /CA pin to the emulator.

The following shows the procedures recovered from the U standby state.
1. In the software standby mode, when the /CA pin is asserted, the emulator enters the U standby
state and the message box shown in figure 2.6 is displayed. To cancel the U standby state, be
sure to end the message box before asserting /RESETP from the user system.
2. Turn Vcc (main) off.

3. Assert /RESETP and turn Vcc (main) on.
4. After the power has been stable, negate the /CA pin.
5. Negate /RESETP, and the U standby state is cancelled.
6. Before the program execution is restarted from the reset vector, the E10A-USB debugging
function, which has been set in the [Recovery Information] page in the [Configuration] dialog
box, is recovered. During this period, the HEW cannot operate.
Notes: 1. For entering or canceling the U standby state, refer to the section of low power mode
in the SH7339 Hardware Manual.
2. When Vcc (main) is turned on in the U standby state, set the TCK value to less than
the number of peripheral module clocks and select [Configuration dialog information]
in the [Recovery Information] page. If this is not selected, the TCK value will be as
follows:
When HS0005KCU01H or HS0005KCU02H is used: TCK = 0.625 MHz
3. After the /CA pin has been negated, if /RESETP is not input for about 30 seconds, a
timeout error will occur.
4. Software breakpoints that have recovered from the U standby state remain to be set on
the memory. However, the contents displayed in the [Breakpoint] sheet of the
[Eventpoint] window may be different from the actual points when the contents of
memory are initialized by the control of Vcc (main). In this case, clear all the
breakpoints and set them again.
5. In functions for which conditions were not recovered by a selection in [Recovery
information], the settings made will not be the same as the contents displayed in a
dialog box or command after the recovery from the U standby state until when the
user program is halted.
6. If [User] is set in the [UBC mode] list box in the [Configuration] dialog box, Break
Condition (UBC) and Trace Acquisition Condition (AUD) cannot be selected.
7. A noise filter is provided in the emulator to prevent malfunction due to noises of the
/CA pin. It takes about 70 ns from assertion (negation) of /CA to reflection to the
emulator. Therefore, set 70 ns or more periods during assertion to negation of /CA.
8. When the U standby state has been cancelled, before the program execution is
restarted from the reset vector, the E10A-USB debugging function, which has been set
in the [Recovery Information] page in the [Configuration] dialog box, is recovered.
During this period, the HEW cannot operate.
When the debugging functions except for [Configuration dialog information] are not
recovered in the [Recovery Information] page, the following waiting time will be
generated before the user program is reexecuted:
Frequency: 833 MHz (Pentium® III)
OS: Windows 2000
Operating state of SH7339: 20-MHz input clock, 1.25-MHz TCK value
Waiting time: Approximately 28 ms
