IMPORTANT
Notes on Downloading Firmware:
• Before using this product for the first time, it is necessary to download the dedicated firmware
(control software built into the PC7501). Please note that, to do this, it is necessary to start up the
PC7501 in the maintenance mode. For firmware download procedures, see "4.2 Downloading
Firmware" (page 46). 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 self-checks are not completed successfully, there may
be trouble with the product. In such case, contact your sales representative. However, perform self-
checks while not connecting the target system.
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 3.0 - 3.6 V, 4.2 - 5.5 V.
•Do not change the voltage of the target system after turning on the power.
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.
Note on Final Evaluation:
• Be sure to evaluate your system with an MCU for evaluation purposes. Before starting mask
production, evaluate your system and make final confirmation with a CS (Commercial Sample)
version MCU.
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 PC7501's upper panel is lit).
Note on RDY* Input:
•Be sure to input "L" to the RDY* pin of the target system during the user program executing (only
while the RUN status LED on the PC7501's upper panel is lit). Inputting "L" to the RDY* pin during
the user program stopping may cause a malfunction of the emulator.
Note on HOLD* Input:
• Be sure to input "L" to the HOLD* pin of the target system during the user program executing (only
while the RUN status LED on the PC7501's upper panel is lit). Inputting "L" to the HOLD* pin
during the user program stopping may cause a malfunction of the emulator.
