(5) Referring MCU STATUS
It is possible to confirm each level of BYTE, CNVSS, RDY*, HOLD*, NMI* pins on the target
system.
IMPORTANT
Notes on MCU STATUS:
• The status of pins of 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.
4.4 Self-checks
(1) Self-check Procedure
To run the emulator self-checks, do so as explained here below. While self-checks are in progress,
LEDs will change as shown in Figure 4.4.
(1) When the target system is connected, disconnect it.
(2) Within 2 seconds of activating power to the emulator, press the RESET switch on the emulator
front panel to switch the emulator to the maintenance mode.
(3) Check the "SAFE" LED starts flashing and then press the RESET switch again.
(4) The self-checks will start. If the normal result is displayed in about 30 seconds, self-checks
terminated normally.
(2) If an Error is Detected in Self-checks
If self-checks do not result normally (ERROR 1 to ERROR 4 in Figure 4.4), check the following.
• Recheck the connection of the emulation probe and PC7501.
•Redownload the proper firmware.
CAUTION
Note on Self-checks:
• If self-checks do not result normally (excluding target system errors), the emulation
probe may be damaged. Then contact your local distributor.
