(5) Referring MCU STATUS

It is possible to confirm each level of pins BYTE, CNVSS, RDY*, HOLD*, NMI* on the target
system.
Notes on MCU STATUS:

4.4 Self-check

(1) Self-check Procedure

To run the emulator self-check, do so as explained here below. While the self-check is in progress,
LEDs will change as shown in Figure 4.4.

(2) If an Error is Detected in the Self-check

If the self-check does not result normally (ERROR 1 to ERROR 4 in Figure 4.4), check the following.
Note on the Self-check:
• The status of pins of an MCU is displayed in the "MCU STATUS" of the EMEM
dialog box. Confirm if it matches with the processor mode.
• Check that "RDY*" and "HOLD*" are set to "H". If they are set to the "L" level, the
MCU itself is in the standby state. The emulator debugger displays an error message
because it receives no response from the MCU.
(1) If the target system is connected, disconnect it.
(2) Within 2 seconds of activating power to the emulator, press the system reset switch on the
emulator upper panel to switch the emulator to maintenance mode.
(3) Check the "SAFE" LED starts flashing and then press the system reset switch again.
(4) The self-check will start. If the normal result is displayed in about 30 seconds, the self-check
terminated normally.
• Recheck the connection of the emulation probe and PC7501.
• Redownload the proper firmware.
• If the self-check does not result normally (excluding target system errors), the
emulation probe may be damaged. Then contact your local distributor.
