IMPORTANT
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 the maintenance mode. For firmware download procedures, see
"4.2 Downloading Firmware" (page 40). Once the firmware has been downloaded, the product can
be used by simply turning on the power.
• Do not shut off the power while downloading the firmware. If this happens, the product will not
start up properly. If power is shut off unexpectedly, redownload the firmware.
• Except when a target status error occurs, if the self-check is not completed successfully, there may
be trouble with the product. In such case, contact your sales representative. However, perform the
self-check in the below setup.
(1) Target system: Not connected
(2) Emulation pod internal switches: At their factory settings
Notes on Target System:
• The Vcc pin of emulator is connected to the target system to observe the voltage of the target system.
Therefore design your system so that the emulator MCU is powered by the target system.
• The voltage of the target system should be within the range of the MCU specification.
•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.
• Is the power supplied? Check that target status LED (POWER) is ON.
For details, refer to "Chapter 4. Usage" (page 37).
Note on Reset Input:
• The reset input from the target system is accepted only while a user program is being executed (only
while the RUN status LED on the PC4701's front panel is lit).
Note on When the Emulator Debugger Ends:
• To restart the emulator debugger after it ends, always shut power to the emulator module off once
and then on again.
Notes on Watchdog Function:
• The MCU's watchdog timer can be used only while programs are being executed. To use it
otherwise, disable the timer.
• If the reset circuit of the target system has a watchdog timer, disable it when using the emulator.
