8. Frequently Asked Questions

8.1

rred at startup, confirm the following.

1) The USB cable and user system interface cable are correctly connected.

2) The power is supplied to the CPU board when an external power source is used.

Turn on the power after the message, 'Turn on the target device and press the <Enter> key.' appears.

3) The selected device corresponds to the microcomputer in use.

8.2. A communication error has occurred during debugging

If a communication error has occurred during debugging, confirm the following.

1) The firmware may have gone out of control due to user program execution (going out of control or accessing to

the monitor area). Disconnect the USB cable of the E8 emulator from the host computer, connect it again, and

then restart the emulator software.

2) The user program does not access the area or the resource used by the firmware.

8.3. Do the on-chip peripheral modules work after a break occurs?

While the program is stopped due to a break, the CPU does not accept interrupts but the peripheral modules continue

operation. For example, when the user program stops due to a break after a timer has started counting, the timer

continues counting but the CPU does not accept timer interrupts.

8.4. Is there any method to check if the emulator fails?

The diagnostic hardware program (self-check program) is available. For the procedure, refer to the section 'Diagnostic

Hardware Program' in the E8 Emulator User's Manual.
