2.6 Connecting the E30A Emulator and the User System
2.6.1 Using the Coaxial Connecto r
(1) Processing NS D pi n
Pull up NSD pin of the target MCU to Vcc1 with a 4.7kΩ resistor. (It cannot be connected directly to Vcc1 and Vcc2.)
Furthermore, be sure that the wiring from NSD pin to the connector is shortest possible.
(2) Mounting part in place
Mount the coaxial connector included with the product (HRM-300-126B(40) made by Hirose Electric) on designated
position of the user system.
(3) Connection procedure
Plug the 50Ω coaxial cable (gray) included with the product into the E 30A emulator and the coaxia l connector on the user
system.
Although the cable can be connected over a distance, the power supply condition of the user system cannot be monitored.
Furthermore, since only a software reset is possible from the E30A emulator, a hardware reset is required when the emulator
debugger is started or when a communication error occurs. Figure 2.4 is a connection diagram showing how to connect the
E30A emulator and user system using the coaxial connector.

2.6.3 Using the Option Board R0E0003 0ACKZ10
(1) Processing NS D pi n
Pull up NSD pin of the target MCU to Vcc1 with a 4.7kΩ resistor. (It cannot be connected directly to Vcc1 and Vcc2.)
Furthermore, be sure that the wiring from NSD pin to the connector (pin 4) is shortest possible.
(2) Mounting part in place
Mount the 2.54mm pitch 8-pin socket included with the product (PIC-FS08-G+R made by Honda Tsushin Kogyo) on
designated position of the user system. Furthermore, mount the 2.54mm pitch 8-pin straight pin included with the product
(PIC-MSA08-2G made by Honda Tsushin Kogyo) on CN4 (solder side) of the option board.
(3) Wiring of Vcc1 and Vcc2
Vcc1 (pin 1) is used to monitor the power supply condition of the user system and as power supply for the RST# and
RSTMSK output buffers.
Vcc2 (pin 2) monitors the power supply condition of the user system.
(4) Wiring of RST# and RSTM SK
Since the target MCU is reset in hardware from the E30A emulator, con nect RST# signal (pin 6) to the RESET# terminal
of the target MCU.
If the reset circuit of the user system uses an open-drain output, pull it up to Vcc1 with a 4.7k–22kΩ resistor. The same
applies for the power-on reset case making use of a CR circuit.
If the reset signal is generated as CMOS output from other logic devices, the user system may have a RSTMSK signal
connected to disable the output. Since RSTMSK input is indeterminate when the E30A emulator is not connected, it
requires a pulldow n resi st or .
(5) Connection procedure
Plug the 10-pin flat cable includ ed with the product into CN3 on the option board.
Plug the 50Ω coaxial cable (gray) included with the product into CN1 on the coaxial converter board.
Fit CN2 on the coaxial converter board into CN2 on the option board. It can be turned 180 degrees as it is fitted into place.
Fit CN4 on the option board into the 8-pin socket on the user system.
Alternatively, the coaxial converter board can be attached to pins 3-5 of the 8-pin socket on the user system without using
the option board .
(6) Compatibility with the E30 emulator (old product)
If you have hitherto been using the 8-pin flat cable of the E30 emulator, you can attach the 2.54mm pitch 8-pin right angle
connector included with the product (FFC-8LAMEP1B made by Honda Tsushin Kogyo) to CN4 (component side) of the
option board, for connection to the user system. However, since the non-coaxial NSD wiring becomes longer, it is
recommended that the connector on the user system be replaced with the 8-pin socket, and that the 8-pin straight pin be
used for connectio n.

3.2.3 Emulator Tab
This tab permits you to specify the clock supplied to the target MCU and data acquisition interval of the RAM monitor.
(1) Clock
Specify the XIN clock and the frequency that supplied to the target MCU.
- Xin: Enter the frequency of the XIN clock, and select Generated (Internal generator circuit) or In ternal (Oscillator circuit
board).
- PLL: Enter the frequency of the MCU’s internal PLL, which should be the same as the value to be set in the user
program.
- CCR: Enter the value for the MCU’s internal clock control register, which should be the same as the value to be set in
the user program.
Notes on Clock Setting:
The emulator sets the PLL-related settings before starting up in order to secure a communication path.
In a user program, be sure to set the same value of the PLL-related settings specified by the emulator
debugger. Otherwise, the emulator will be out of control. The divide ratios of the CPU clock and
peripheral clo ck can be changed in the user prog ram.
The XIN clock is used to enter the debug mode and to stop the user program forcibly. Therefore, do not
stop the XIN clock in the user program.
The PLL clock divided by the base clock divider is used for communication between the emulator and
the MCU. Therefore, do not change the PLL frequency and the divide ratio of the base clock in the user
program.
When the emulator is connected, the PLL clock stop bits are ignored. Therefore, the PLL keeps
oscillating even when the WAIT or STOP instruction is executed. This means that BCLK is also
oscillating, so that control returns from WAIT or STOP by an INT8, 7 or 6 or other interrupt request.
The clock can be switched to a low speed clock (f256, fC, fOCO4). However, as the CPU operation
clock becomes slower, the response speed of the emulator debugger becomes also slower.
Furthermore, the internal flash ROM cannot be rewritten during a low speed clock operation. Therefore,
do not use software breaks.

(2) Data acquisition interval in MCU running state (1 - 100) ms
Specify the data acquisition interval (b yte or word data). At this interval the functions such as the RAM monitor acquire
the memory data while the user program is running. 1 - 100 ms can be specified.
Note on Data Acquisition during MCU Execution:
Using a function that acquires the memory data during user program execution, such as RAM monitor
function, results in the realtime capability becoming impaired because the debug monitor program
intervenes. Also, in order to complete processing of the debug monitor program as fast as possible, do
not operate the MCU’s internal DMA du ring the processing.
(3) Do not communicate with MCU while target is executing.
Specify whether or not to communicate with the MCU when executing a user program. While the user program is running,
the emulator communicates with the MCU, for example, to check the operating status of the MCU, or to receive the trace
information from the MCU.
The PLL clock divided by the base clock divider is used for communication between the emulator and the MCU.
Therefore, when executing the STOP or WAIT instruction, or when temporarily switching to the PLL self-oscillation
mode, select this check box to avoid communication breakdown. The debug function cannot be used because the emulator
does not communicate with the MCU when executing the user program. However, it is possible to press the stop button
after restored to the base clock specified in the Clock column.
3.2.4 Script Tab
This tab permits you to specify a script file.
(1) Init File
If you have any script that is automatically executed at startup, specify that file.
- Click the “Refer…” button to open the Select Script File dialog box.
- Select the desired script file.

4. Debugging Functions
4.1 Break Function
4.1.1 Software Break
If the breakpoint you set is a software breakpoint, the program stops before executing the instruction at the set breakpoint
- Up to 256 break points can be set.
- You can specify breakpoints in the internal RAM of the MCU, the internal flash ROM of the MCU, and the RAM on the
user system.
- If breakpoints in the internal flash ROM of the MCU are specified, the need arises for instruction rewrite/writeback
processing in bl ock u ni ts .
4.1.2 Execution Address Break
This is a kind of event break by the internal debug circuit of the MCU. It specifically is a pre-execution break that causes
execution of the user program to stop at a specified address.
- Up to 8 break points can be set (used for hardwa re breaks, trace points, and time measurement events in common).
- Since there is no need for instruction rewrite/writeback processing, the response speed is fast.
4.1.3 Hardware Break
This is a kind of event break by the internal debug circuit of the MCU. It specifically is a post-execution break that causes
execution of the user program to stop upon detecting data access at a specified address.
- Up to 8 break points can be set (used for execution address breaks, trace points, and time measurement events in common).
- You can set a specified address range (using 2 events).
- You can set three conditions, e.g., read, write, and read/write.
- Only one instance of data comparison break can be specified (event E5 only). Several bytes from the beginning of the
MCU’s internal RAM (8 bytes at the addresses 0400h -- 0407h) are used for data comparison by the debug monitor program.
These bytes cannot be used in the user program when using a data comparison break.
Notes on Execution Address Break and Hardware Break:
Do not set breaks in the area designated below. This restriction is due to specifications of the MCU’s
internal debug circuit.
0100 0000h – FEFF FFFFh
Note on Data Comparison Break:
For data comparison break, the debug monitor program compares the data after the debug interrupt
occurs at the specified address to determine whether or not to cause a break. Using this function results
in the realtime capability becoming impaired because the debug monitor program intervenes. Also, in
order to complete processing of the debug monitor program as fast as possible, do not operate the
MCU’s internal DMA during the proce ssing.
In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz and CPU 64MHz, for example, it takes
6μs to return to the user program after the data compari son results in a mismatch.
4.1.4 Break Combination
Event breaks by the internal deb ug circuit o f the MCU can be cascad ed to constitu te a state transition break at up to 8 points in
the forward direction. If all o f the ev ents are us ed fo r a state transitio n br eak, program executio n will br eak wh en the even ts E7,
E6, ..., and E0 all have occurred in that order.

4.2 Trace Function
4.2.1 Trace Capacity
The following can be selected depending on the trace mode chosen in the event setting window.
- Trace priority
8M events can be traced. The trace information is output from the MCU and recorded to the emulator trace memory. The
user program execution may be delayed depending on the event occurrence interval because the MCU processes the trace
information output prior to others.
- MCU execution priority
512 events can be traced. The trace information is recorded to the trace RAM of the MCU’s internal debug circuit.
Therefore, this mode does not affect the execution speed of the user program.
Note on Affect on User Program in Trace Priority Mode:
In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz and CPU 64MHz, for example, it takes
5μs to output trace information for each event. If the average of event occurrence interval among 512
events is less than 5μs, the CPU operation will be suspended, because the trace information is output
via the trace RAM of the MCU’s internal debug circuit.
4.2.2 Trace Contents
You can select information on branch sources and destinations, information on conditional branches, information on data
accesses, or mixed information of branch sources and destinations, and data accesses.
- Information on branch sources and destinations
Branch source address and branch destination address are recorded as an event.
- Conditional br anch in fo rmation
Branch infor mation (su ccess /failur e of condition al branc hes) are re corded in a co mpr essed format. Up to 48 of cond itiona l
branches are recorded as an event, so that the communication amount of the trace information can be reduced and the
affect on execution speed of the user program can be reduced even in trace priority mode.
To record conditional branch information, cancel all trace event settings in the event setting window. An unused event can
be used as a break event.
- Data access information
Address, data, data size and read/write information are recorded as an event.
Note on Jump in Queue:
R32C/100 series has a function that branches to the instructions fetched into the prefetch queue, to
improve the processing pe rformance, but the branch source and destination info rmation is not output.
Notes on the Data Acces s Trace:
16-bit word data starting from an odd address and 32-bit long word data assigned differently from the 4-
byte alignment cannot be traced properl y .
Data access event by DMA is not the subject of detection.

4.2.3 Extraction Trace
An extraction trace with the start event E0 and the end event E4 specified is possible.
The events E1 -- E3 or E5 -- E7 that occurred during an interval between E0 to E4 are recorded in the trace RAM.
Note on Execution Address Trace Event:
When specifying the execution address as the trace event, the results may be different from what you
expect because the event is encou ntered at the prefetch address.
Note on Trace Event:
Do not set events in the area designated below. This restriction is due to specifications of the MCU’s
internal debug circuit.
0100 0000h – FEFF FFFFh
4.3 Time Measument Function
4.3.1 Execution Time Measurement
You can measure a program execution time between Go and Stop. The 32-bit CPU clock counter allows you to measure a
program execution time of up to 67.1 s when operating at 64MHz.
4.3.2 Section Time Measurement
You can measure a program execution time between data accesses by trace information. Data access trace information (address,
data, data size and read/write) is compared/detected as the measurement start event and measurement end event inside the
emulator. The 40-bit asynchronous clock counter inside the emulator enables the section time measurement of more than 24
hours.
As a condition of section time measurement, you can specify that the measurement be taken of a time from when the start
event occurs till when the end event occurs or a cycle time with which individual events occur.
Notes on Time Measurement Function:
The execution time and the section time cannot be measured simultaneously. Select either an
execution time measurement or a section time measu reme nt.
In a section time measurement performed, the data access trace information output from the MCU is
compared in the emulator to detect the start and end events. If a large number of data access times is
specified, trace output will take a lot of time, leading to errors in section time measurement or affecting
execution speed of the user program.
In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz, for example, it takes 5μs to output the
data access trace information for each event. If a data access of less than 5μs occurs, a trace output
time-dependent error will occur. Furthermore, if such a short data access occurs frequently, execution
speed of the user program will be delayed. We recommend write-only settings with least possible
events.

Dec 01, 2010
4.4 RAM Monitor Function
You can view memory data during user program execution by a pseudo-RAM monitor function which is realized by the
software using event E5. Data is acquired in byte/word unit by the interval specified in “Data acquisition interval in MCU
running state” in the Emulator tab of the Init d ialog box.
Notes on RAM Monitor Function:
The RAM monitor function results in the realtime capability becoming impaired because the debug
monitor program intervenes. Also, in order to complete processing of the debug monitor program as fast
as possible, do not operate the MCU’ s internal DMA during the processing.
For the RAM monitor function, the emulator generates a debug interrupt and the debug monitor
program sends the data to return control to the user p rog ram.
In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz and CPU 64MHz, for example, it takes
6μs from the debug interrupt occurred to return to the user program.
The RAM monitor function should be adjusted for sampling intervals (byte/word data acquisition
intervals in ms units) during user program execution. Since the updating time is extended if a wide area
is displayed in bytes, we recommend displayin g only the necessa ry area in word size.

Appendix B Differences between the Actual MCU and Emulator
Differences between the actual MCU and emulator are shown below. When debugging the MCU using this product, be careful
about the following precautions.
Notes on Clock Setting:
The emulator sets the PLL-related settings before starting up in order to secure a communication path.
In a user program, be sure to set the same value of the PLL-related settings specified by the emulator
debugger. Otherwise, the emulator will be out of control. The divide ratios of the CPU clock and
peripheral clo ck can be changed in the user prog ram.
The XIN clock is used to enter the debug mode and to stop the user program forcibly. Therefore, do not
stop the XIN clock in the user program.
The PLL clock divided by the base clock divider is used for communication between the emulator and
the MCU. Therefore, do not change the PLL frequency and the divide ratio of the base clock in the user
program.
When the emulator is connected, the PLL clock stop bits are ignored. Therefore, the PLL keeps
oscillating even when the WAIT or STOP instruction is executed. This means that BCLK is also
oscillating, so that control returns from WAIT or STOP by an INT8, 7 or 6 or other interrupt request.
The clock can be switched to a low speed clock (f256, fC, fOCO4). However, as the CPU operation
clock becomes slower, the response speed of the emulator debugger becomes also slower.
Furthermore, the internal flash ROM cannot be rewritten during a low speed clock operation. Therefore,
do not use software breaks.
Notes on Interrupt Stack:
The E30A Emulator uses an interrupt stack of up to 52 bytes. Make sure sufficient space is reserved for
the interrupt stack area, with the maximum stack size used by a user program added. If the reserved
interrupt stack area is exceeded, the user program may go wild or the emulator may be out of control.
The E30A Emulator sets the interrupt stack pointer (ISP) at the beginning address of RAM + 0100h
after being reset, and uses that location as a stack area at deassertion of reset.
Note on Interrupts That Cannot be Used by the User Program:
The BRK2 interrupt, single-step interrupt, and DBC interrupt are used by the emulator program.
Therefore, make sure the user prog ram does not use these interrupts.
Note on Interrupt Reque st:
Even if a user program is not being executed (including when run-time debugging is being performed),
the peripheral I/O such as a timer keeps running. The interrupt request cannot be accepted, because
the emulator disables interrupts. The interrupt request is accepted immediately after the user program
execution is started.
Note on Low Voltage Detection Interrupt:
With this product, as the power voltage cannot be changed after powering on the user system, the low
voltage detection interrupt cannot be used.
Notes on Using the Watchdog Timer:
A user program can be debugged by using the MCU’s internal watchdog timer if so desired. When the
watchdog timer is active, the debug monitor program refreshes it as necessary.
Watchdog timers connected external to the MCU cannot be used. Make sure those watchdog timers are
disabled while the emulator is in u se.

Note on the Lock Bits for the MCU Internal Flash ROM:
The lock bits for the blocks whose contents have been altered by downloading a user program or
setting software breakpoints are in an unlocked state.
Note on Protect Bit 2 (PRC2):
Protect bit 2 (PRC2) behaves in such a way that when the bit is set to 1 to remove write protect and
then a write to any address is executed, the bit is write protected again. Note that the bit cannot be
cleared by a software operation while single-stepping a program or manipulating the memory window.
Note on RDY# Input:
Be sure to input "L" to pin RDY# of the user system during the user program executing (when the RUN
status LED is lit). Inputting "L" to pin RDY# during the user program stopping may cause a malfunction
of the emulator.
Note on HOLD# Input:
Be sure to input "L" to pin HOLD# of the user system during the user program executing (when the RUN
status LED is lit). Inputting "L" to pin HOLD# during the user program stopping may cause a malfunction
of the emulator.
Note on the MCU Used in Debugging:
During debugging, the MCU’s internal flash ROM is frequently rewritten as a user program is
downloaded or software breakpoints are set or cleared. Do not use any MCU in product once it was
used in debugging.
Note on Final Evaluation:
Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate
your system and make final confi rmatio n with a CS (Commercial Sample) version MCU.

Appendix C Notes on Using This Product
Notes on using this product are listed below. When debugging the MCU using this product, be careful about the following
precautions.
Notes on the Resource s of the MCU Used by the Emulator:
When you are using a data comparison break (event E5 only), the E30A Emulator uses several bytes
from the beginning of the MCU’s internal RAM (8 bytes at the addresses 0400h -- 0407h) for data
comparison by the debug monitor program. These bytes cannot be used in the user program when
using a data compari son break.
The E30A Emulator uses approximately 1.2 Kbyte of the internal RAM as needed, for example, to
download a user program. Since the memory contents are saved in advance, you do not need to be
specifically concerned, except that you cannot specify any area that overlaps the interrupt stack and an
area on which DMA operates.
Notes on Power Supply to the User System:
The emulator does not supply power to the user system. Provide power to the user system separately.
Do not change the voltage of the user system after turning on the powe r.
Note on Downloading Firm ware:
Do not shut off the power while downloading the firmware. If this happens, the product will not start up
properly. If the power is shut off unexpectedly, startup the emulator in maintenance mode and
redownload the firmware.
Note on Quitting the Emulator Debugger:
To restart the emulator debugger, always shut power to the emulator and user system off once and
then on again.
Note on Event Settings:
Events are used for breaks, trace, and time measurement in common. For breakpoint settings in the
source window, events are given priority in order to reduce the number of times the flash ROM is
rewritten. Note that the unused events are use d in order of followings.
(Extraction start event E0, end of range event E4, and data comparison event E5 are assigned lower
priorities.)
E7 -> E6 -> E3 -> E2 -> E1 -> E5 -> E4 -> E0
Notes on the Software Breaks:
Software breaks execute the tool-only BRK2 command instead of instruction code to generate a BRK
interrupt. Be aware that when trace results are referred to in bus display, you will see “BFh” displayed
for instruction fetches performed at the addresse s that have software breakpoints set.
If a user program is altered before being downloaded, the software breakpoints that have been set may
be displaced depending on the content of alteration. After downloading a user program, be sure to
check the contents of soft ware breakpoints set.
Notes on the Data Acces s Trace:
16-bit word data starting from an odd address and 32-bit long word data assigned differently from the 4-
byte alignment cannot be traced properl y .
Data access event by DMA is not the subject of detection.

Notes on Debug Monitor Program Intervention:
The following functions result in the realtime capability becoming impaired because the debug monitor
program intervenes. Also, in order to complete processing of the debug monitor program as fast as
possible, do not operate the MCU’s internal DMA during the processing.
- Run-time debuggi ng (Referring and modifying the memory during user program execution)
- RAM monitor
- Data comparison break (when a break for data access is set in event E5)
The RAM monitor function should be adjusted for sampling intervals (byte/word data acquisition
intervals in ms units) during user program execution. Since the updating time is extended if a wide area
is displayed in bytes, we recommend displayin g only the necessa ry area in word size.
Note on Trace Mode:
When selecting Trace priority, the user program execution may be delayed depending on the event
occurrence interval because the MCU processes the trace informati on output prior to others.
When selecting MCU exe c ution priority, the execution speed of the user program is not affected.
Notes on the Simultaneous Use of Multiple Functions:
Data comparison breaks and RAM monitor cannot be used at the same time. If event E5 is set for a
data access break, the RAM monitor functions cannot be specified. If the RAM monitor function needs
to be used, event E5 cannot be specified for a data access brea k.
Be aware that if a run-time debug, RAM monitor, or data comparison break is used during a branch
trace in which branch addresses are recorded, the recorded information will include branch information
(debug monitor program processing address) whi ch the user program does not gene rate.
Note on Debugging in the Stop Mode or Wait Mode:
While the user program is running, the emulator communicates with the MCU, for example, to check the
operating status of the MCU, or to receive the trace i nformatio n from the MCU.
The PLL clock divided by the base clock divider is used for communication between the emulator and
the MCU. Therefore, when executing the STOP or WAIT instruction, or when temporarily switching to
the PLL self-oscillation mode, select the check box “Do not communicate with MCU while target is
executing” to avoid communication breakdown. The debug function cannot be used because the
emulator does not communicate with the MCU when executing the user program. However, it is
possible to press the stop button after restored to the base clock specified in the Clock column.
When the emulator is connected, the PLL clock stop bits are ignored. Therefore, the PLL keeps
oscillating even when the WAIT or STOP instruction is executed. This means that BCLK is also
oscillating, so that control returns from WAIT or STOP by an INT8, 7 or 6 or other interrupt request.
Note on MCU Reset:
Software reset and hardware reset cannot be used during the user program execution. If the MCU is
reset during the user program execution, the emulator recovers communication with the MCU and the
user program stops in a reset state.

Notes on Debugging in CPU Rewrite Mode:
To debug a program in CPU rewrite mode, check the box “Debug the program using the CPU Rewrite
Mode” in the MCU tab of the Init dialog box. When the debugging in CPU rewrite mode is enabled,
software breakpoint to the internal ROM area cannot be used.
Do not stop the user program during debugging in CPU rewrite mode. Otherwise, the emulator will be
out of control. Furthermore, before executing a user program, be sure to disable automatic updating of
the windows to ensure that no memory accesses will occur during execution of the user program. To
inspect data after CPU rewrite operation, stop the program after exiting CPU rewrite mode and inspect
the data in the memory window or a nother appropriate windo w.
Note on Debugging of E2dataFlash:
When you are debugging the E2dataFlash, do not stop the user program during operating the
E2dataFlash. Otherwise, as the operation to the E2dataFlash will be suspended, it may not be
processed properly even though the user program is restarted. Furthermore, before executing the user
program, be sure to disable automatic updating of the windows to ensure that no accesses to the
E2dataFlash will occur during execution of the user program.
