Notes on Power Supply to the Target System:
• The Vcc pin of the emulator is connected to the target system to observe the voltage of the target
system. Therefore the emulator cannot supply the power to the target system. 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 and suit to
the emulator MCUs as shown below;
(1) For 5.0V version MCUs: +4.5 to +5.5 V
(2) For 3.3V version MCUs: +3.0 to +3.6 V
•Do not change the voltage of the target system after turning on the power.
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 firmware download procedures, see "4.2 Downloading Firmware" (page 32). 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 in maintenance mode.
• Be sure to disconnect the target system before downloading the firmware.
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 switch 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.
Notes on the Self-check:
• If the self-check does not result normally (except target status errors), the product may be damaged.
Then, contact your local distributor.
•Be sure to disconnect the target system before executing the self-check. For details on the self-
check, see "4.4 Self-check" on page 34.
Note on Quitting the Emulator Debugger:
• 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 evaluation MCU. Before starting mask production,
evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU.
