APPENDIX B PROGRAM WAIT CONTROL REGISTER SETTINGS IN IN-CIRCUIT EMULATOR

When performing programmable debugging using the in-circuit emulator, wait control must be performed by

setting PWC1 and programmable wait control register 2 (PWC2).

If an external wait is set for the internal ROM area, the CPU becomes deadlocked.

The deadlock status is cleared only by reset input.

The settings of PWC2 and PWC1, other than bits 1 and 0, are invalid in the actual device, but have no adverse

effect.
