IMPORTANT
Notes on Downloading Firmware:
• Before using this product for the first time, it is necessary to download the dedicated firmware.
Please note that, to do this, it is necessary to start up the emulator main unit in maintenance mode.
For downloading firmware, see "4.2 Downloading Firmware" (page 48). 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 the power is shut off unexpectedly, redownload the firmware.
• Download the firmware with the target system not connected.
Note on Final Evaluation:
• Be sure to evaluate your system with an evaluation MCU. Before starting mask production,
evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU.
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 Power Supply to the Target System:
• Pins Vcc1 and Vcc2 are connected to the target system to observe the voltage. Therefore, the power
is not supplied to the target system from the emulator, design your system so that the target system
is powered separately.
• The voltage of the target system should be as follows.
(1) When JP1 is set as Vcc1 = Vcc2:
2.7 V ≤ Vcc1 = Vcc2 ≤ 5.5 V
(2) When JP1 is set as Vcc1 > Vcc2:
4.8 V ≤ Vcc1 ≤ 5.2 V
2.7 V ≤ Vcc2 < Vcc1
•Do not change the voltage of the target system after turning on the power.
Notes on Self-check:
• If the self-check does not result normally (excluding target system errors), the emulation probe may
be damaged. Then contact your local distributor.
• Run the self-check with the target system not connected.
Note on RESET* Input:
•A low input to pin RESET* from the target system is accepted only when a user program is being
executed (when the RUN status LED on the PC7501's front panel is lit).
