( 9 / 68 )
IMPORTANT
Note on Malfunctions in the PC4701 System:
• If the emulator malfunctions because of interference like external noise, do the following to remedy
the trouble.
(1) Press the RESET button on the emulator front panel.
(2) If normal operation is not restored after step (1), shut OFF power to the emulator once and then
reactivate it.
Note for PC4700 System:
• PC4700H products whose serial number ends with a number or D, DE, G cannot be used with the
M37641T2-RPD-E.
Example: 5KE100, 5KE100D, 5KE11DE, 5KE100G
Do NOT use it with the M37641T2-RPD-E. The PC4700 needs upgrading.
Example: 5LE123B
You can use it with the M37641T2-RPD-E.
Notes on Downloading Firmware:
• Before using this product for the first time, it is necessary to download the dedicated firmware
(control software for the emulation pod built into the PC4701). Please note that, to do this, it is
necessary to start up the PC4701 in maintenance mode. For firmware download procedures, see
"4.2 Downloading Firmware" (page 40). Once firmware has been downloaded, the product can be
used by simply turning on the power.
• Do not shut off the power while downloading firmware. If this happens, the product will not start
up properly. If power is shut off unexpectedly, redownload firmware.
• Except when a target status error occurs, if self-check is not completed successfully, there may be
trouble with the product. In such case, contact your local distributor. However, perform the selfcheck in the below setup.
(1) Target system: Not connected
(2) Emulation pod internal switches: At their factory settings
Note on Map Settings (MAP Command):
•Always set the SFR area and the internal RAM area to EXT.
When you debug an MCU with flash memory, however, set addresses 0470H through 0FFFH to
INT. (The internal RAM size of the on-board evaluation MCU is 1 KB.) Because the internal RAM
size of the evaluation MCU is smaller than the RAM size of MCUs with flash memory, allocate
emulation memory.
You can set the mapping by issuing the MAP command in the script window of the emulator
debugger.
Example (when using an MCU with flash memory in the memory expansion mode):
MAP 0000,046F,EXT (SFR area and internal RAM area)
MAP 0470,0FFF,INT (Internal RAM area extended by emulation memory)
MAP 1000,7FFF,EXT (External area)
MAP 8000,FFFF,INT (Internal ROM area)
( 10 / 68 )
Notes on the Target System:
• As pin Vcc of emulator is connected to the target system to observe the voltage of the target system,
the target system is not powered by the emulator. Therefore design your system so that the target
system is powered separately.
• The voltage of the target system should be within the range of the MCU specification and +3.0 to
+3.6 V or +4.5 to 5.25 V.
•Do not change the voltage of the target system after turning on the power.
• Before powering on your emulator system, check that the host machine, the emulator main unit,
the converter board and target system are all connected correctly. Next, turn on the power to each
equipment following the procedure below.
(1) Turn ON/OFF the target system and the PC4701 emulator as simultaneously as possible.
(2) When the PC4701 and emulator debugger start up, check the target status LEDs on the
emulator main unit's front panel to see if this product is ready to operate.
(For the target status LEDs on the front panel when starting up the PC4701, refer to "4.1 (3)
LED Display When the PC4701 Starts Up Normally" on page 39)
Note on SYNCOUT Output:
IMPORTANT
•When using the emulator, SYNCOUT signals are not output.
Note on Reset Input from the Target System:
• If a reset is input from the target system, when a user program is being executed (when the RUN
status LED on the PC4701's front panel is lit), the user program is stopped.
Note on RDY Input:
• Be sure to input "L" to pin RDY* of the target system during the user program execution. Inputting
"L" to pin RDY* while the user program is stopped may cause a malfunction of the emulator.
Note on HOLD Input:
• Be sure to input "L" to pin HOLD* of the target system during the user program execution. Inputting
"L" to pin HOLD while the user program is stopped may cause a malfunction of the emulator.
( 11 / 68 )
IMPORTANT
Note on Differences between the Actual MCU and Emulator:
•Emulator operation differs from mask MCU operation as listed below.
(1) Reset condition
(2) Power voltage
When using the emulator, it is not possible to use with the range of 4.15 to 4.5 V.
(3) Initial values of internal resources data at power-on
(3) Internal memory (ROM and RAM) capacities, etc.
(4) Ports P0, P1, P2, P3 and P40
Some I/O ports (P0, P1, P2, P3 and P40) of the M37641T2-RPD-E are connected to the target
system via the port emulation circuit in the M37641T2-RPD-E. Therefore, the external bus
timing and the electrical characteristics are slightly different from those of the actual MCU.
For the differences of the I/O timing etc. between the emulator and the actual MCU, refer to
"5.2 Connection Diagrams" (page 47) and "5.3 Operation Timing" (page 49).
Table 1.1 lists the differences of the I/O level between the emulator and the MCU.

Make note that in the oscillator circuit where a resonator is connected between pins XIN and
XOUT, oscillation does not occur because a flexible cable, buffer IC and other devices are
used between the evaluation MCU and the target system. See "Figure 3.10 Circuit in which
oscillation does not occur (same for XCIN-XCOUT)" (page 31).
(7) Pins XCIN and XCOUT
Make note that in the oscillator circuit where a resonator is connected between pins XCIN and
XCOUT, oscillation does not occur because a flexible cable, buffer IC and other devices are
used between the evaluation MCU and the target system. See "Figure 3.10 Circuit in which
oscillation does not occur (same for XCIN-XCOUT)" (page 31).
(8) Pin SYNCOUT
Make note that pin SYNCOUT does not output data.
(9) Pins D+, D-, Ext. Cap, LPF, AVcc and AVss
Refer to "3.4 Connecting USB-related Signals" (page 28).
(10) Other pins
As a flexible cable is used between the evaluation MCU and the target system, some
characteristics are slightly different from those of the actual MCU.
Therefore, be sure to evaluate your system with an evaluation MCU. Before starting
mask production, evaluate your system and make final confirmation with an ES
(Engineering Sample) version MCU.
( 12 / 68 )
IMPORTANT
Notes on the Watchdog Function:
• The MCU's watchdog timer can be used only while a program is being executed. To use it
otherwise, disable the watchdog timer.
• If the reset circuit of the target system has a watchdog timer, disable it when using the emulator.
Note on DMA Transfer:
•When using the DMA transfer function, pay attention to the following.
(1) Breaks are not executed during the DMA transfer. Break are executed after the DMA transfer
is finished.
(2) The DMA transfer is not executed while a break is executed.
(3) The DMA transfer cannot be executed on the emulation memory. It is possible to transfer only
from the area set to "EXT" to the area set to "EXT" by MAP settings.
(4) In the result of the real-time trace, RD and WR signals during the DMA transfer cycle
displayed as fixed "H". (RD and WR signals output from the MCU change correctly.)
Note on the Key-on Wake Up Function:
• The key-on wakeup interrupt is accepted only during STP command or WIT command execution.
The interrupt is not accepted in any other situations.
( 13 / 68 )
IMPORTANT
Note on Reading MCU Internal Resources:
•When the M37641T2-RPD-E is configured with the emulator debugger, the following results occur
when reading MCU internal resources (SFR and internal RAM area). In both cases, data is not
displayed correctly, but internal data is not affected at all.
(1) Real-time tracing
Data values in the MCU internal resource read cycle are not displayed correctly.
(2) Real-time RAM monitoring
Data values in the MCU internal resource read cycle are not displayed correctly.
Note on a Watch Point:
• When the M37641T2-RPD-E is configured with the emulator debugger, note the following if
specifying a watch point for MCU internal resources (SFR and internal RAM area).
Change the address specified as a watch point so as not to overlap the area set for the real-time RAM
monitor (you can check using the RRAM command of the M3T-PD38). When the address specified
as a watch point overlaps the area set for the real-time RAM monitor and the MCU internal
resources are read out, data will not be displayed correctly. The initial setting of the real-time RAM
monitor is 0000H to 03FFH.
Example:
Watch point ................................0000H
Real-time RAM monitor ............0010H to 040FH
Note on Event Breaks:
•With the emulator debugger you can not use data read out from the MCU internal resources (RAM
and SFR area) as a condition for event breaks.
Note on Software Breaks:
• Software breaks generate BRK interruptions by forcibly inserting a BRK instruction at "00h"
instead of a instruction code. Therefore, when you reference the result of a trace in bus mode, "00h"
is displayed as the instruction fetch address where a software break is set.

IMPORTANT
Note on Stack Area:
• With this product, a maximum 3 bytes of the user stack is consumed as work area.
Note on Quitting the Emulator Debugger:
• To restart the emulator debugger, always shut power to the emulator module off once and then on
again.
Notes on Connecting the Target System:
• When connecting the FLX100 flexible board and the converter board, be careful not to forcibly
press the connector top of the converter board. The flexible board and the converter board are
guaranteed for only 20 insertion/removal iterations.
•Especially be careful not to insert the converter board in a wrong direction.
