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. 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 MPMD pin must be 0 when the emulator is connected and 1 when the emulator is
not connected, respectively.
(1) When the emulator is used: MPMD = 0
(2) When the emulator is not used: MPMD = 1
Figures 1.3 shows an examples of circuits that allow the MPMD pin to be GND (0)
whenever the emulator is connected by using the user system interface cable.
3. When a network resistance is used for pull-up, it may be affected by a noise. Separate
TCK from other resistances.
4. 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 down by a resistance of 1 kilo-ohm and setting PUL15 = 0 in
the PULCR register after a reset.
5. 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.
6. Since the H-UDI and the AUD of the MPU operate with the VccQ, supply only the
VccQ to the UVCC pin. Make the emulator’s switch settings so that the user power
will be supplied (SW2 = 1 and SW3 = 1).
7. The resistance values shown in figure 1.3 are reference.
8. For the pin processing in cases where the emulator is not used, refer to the hardware
manual of the related MPU.
9. For the AUDCK pin, guard the pattern between the H-UDI port connector and the
MPU at GND level.

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 MPMD pin must be 0 when the emulator is connected and 1 when the emulator is
not connected, respectively.
(1) When the emulator is used: MPMD = 0
(2) When the emulator is not used: MPMD = 1
Figures 1.3 shows an examples of circuits that allow the MPMD pin to be GND (0)
whenever the emulator is connected by using the user system interface cable.
3. When a network resistance is used for pull-up, it may be affected by a noise. Separate

3. Low-Power States (Sleep, Software Standby, Module Standby, U Standby, and R Standby)
For low-power consumption, the SH7343 has sleep, software standby, module standby, U
standby, and R standby states.
The sleep, software standby, and module standby states are switched using the SLEEP
instruction. When the emulator is used, the sleep and software standby states can be cleared
with either the normal clearing function or with the [STOP] button, and a break will occur.
Note: The memory must not be accessed or modified in sleep state.
4. Reset Signals
The SH7343 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 SH7343.
Note: Do not break the user program when the /RESETA, /RESETMFI, or /BREQ signal is
being low and the wait control signal is being active. A TIMEOUT error will occur. If
the wait control signal becomes active or the /BREQ 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)
JTAG clock: 10 MHz (TCK clock)
When a one-byte memory is read from the command-line window, the stopping time will be
about 42 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 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 issues a single write to outside. The LRU
is not updated.
•
At memory read: Reads memory from the cache. The LRU is not updated.
Therefore, when memory read or write is performed during user program break, the cache state
does not change.
•
At breakpoint set: Disables the instruction cache.

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
When the MFI boot mode is used, be sure to activate the emulator by setting the MFIINT
signal as a trigger for the MFI transfer from the base-band side.
In the active-through mode, the emulator does not operate during break.

12. 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.
13. Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be 1.25 MHz.

Display and modification
Do not change values of the User Break Controller because it is used by the emulator.
For each RCLK watchdog timer register, there are two registers to be separately used for
write and read operations.

The RCLK watchdog timer operates only when the user program is executed. Do not
change the value of the frequency change register in the [IO] window or [Memory] 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
(SH7343.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.

15. Illegal Instructions
If illegal instructions are executed by STEP-type commands, the emulator cannot go to the
next program counter.
16. [Reset CPU] and [Reset Go] in the [Debug] Menu
When a reset is issued from [Reset CPU] or [Reset Go] in the [Debug] menu, the clock pulse

Software Trace Function:
Note: This function can be supported with SHC/C++ compiler (manufactured by Renesas
Technology Corp.; including OEM and bundle products) V6.0 or later.
However, SHC/C++ compiler (including OEM and bundle products) V8.0 or later is
needed when instructions other than those compatible with SH4 are output.
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 SuperHTM RISC engine C/C++ Compiler,
Assembler, Optimizing Linkage Editor User’s Manual.
When the load module is downloaded on the emulator 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 [Acquire Software trace] radio button in the
[Software trace] dialog box that is opened by double-clicking on the software Trace column of the
[Eventpoint] window.
Note: To cancel settings, select the [Don’t care] radio button in the [Software trace] dialog box

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 branch 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
previously output 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.
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.

Notes: 1. The memory range for which trace is output is the address on the system bus and not
supported for the MMU or cache.
2. In the memory range for output, do not specify the ranges that the user program has
been downloaded or the user program accesses.
3. The range for trace output must be 1 MB or less.
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 SH7343 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.
3. The set value of the JTAG clock (TCK) is initialized by executing [Reset CPU] or [Reset Go].
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 RAM areas in CS0 to CS6 and the internal RAM areas.
However, a BREAKPOINT cannot be set to the following addresses:
•
•
•
•
•
ROM areas in CS0 to CS6
Areas other than the internal RAM
Areas other than CS0 to CS6
A slot instruction of a delayed branch instruction
An area that can be only read by MMU
3. During step operation, BREAKPOINTs are disabled.
4. 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.
5. 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.
6. 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.
7. 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 SH7343 MMU status during command input when the VPMAP_SET
34
Download from Www.Somanuals.com. All Manuals Search And Download.
command setting is disabled. The ASID value of the SH7343 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 SH7343 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.
8. 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 SH7343 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.
9. 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 SH7343 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.
10. 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
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.
11. 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 event condition, the mark z disappears.

1. When [Go to cursor], [Step In], [Step Over], or [Step Out] is selected, the settings of Event
Condition 3 are disabled.
2. When an Event Condition is satisfied, emulation may stop after two or more instructions have
been executed.
3. 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.

(a) Specifying the measurement start/end conditions
Set the performance measurement conditions in the [Action] page after conditions have been
set in the [Event Condition] dialog box that is opened by double-clicking Ch1 to Ch6 and Ch8
to Ch12 on the [Event Condition] sheet of the [Eventpoint] window.
Notes: 1. When no measurement start/end conditions are specified, measurement is started by
executing a program and ended when an event condition is satisfied.
2. When only the measurement start or end condition is specified, performance cannot be
measured. Be sure to specify both of the measurement start and end conditions.
3. When the measurement start/end conditions are specified, step operation cannot be
performed.

Each measurement condition is also counted when conditions in table 2.14 are generated.
Table 2.14 Performance Measurement Conditions to be Counted
Measurement Condition
Notes
No caching due to the
settings of TLB cacheable
bit
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 and memory output 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.
(d) Extension setting of the performance-result storing counter
The 32-bit counter stores the result of performance, and two counters can be used as a 64-bit
counter.
To set a 64-bit counter, check the [Enable] check box in the [Extend counter] group box of the
[Performance Analysis] dialog box for Ch1 and Ch3.
2. Displaying the result of performance
The result of performance is displayed in the [Performance Analysis] window or the
PERFORMANCE_ANALYSIS command in hexadecimal (32 bits).
However, when the extension counter is enabled, it is displayed in hexadecimal (64 bits).
Note: If a performance counter overflows as a result of measurement, “********” will be
displayed.
3. Initializing the measured result
To initialize the measured result, select [Initialize] from the popup menu in the [Performance
Analysis] window or specify INIT with the PERFORMANCE_ANALYSIS command.
