The blank areas are reserved. No access is allowed.
Values after hardware reset, power-on reset, or voltage monitor 0 reset are as follows:
- 00000000b when a low-level signal is input to the CNVSS pin
- 00000010b when a high-level signal is input to the CNVSS pin
Values after voltage monitor 1 reset, voltage monitor 2 reset, software reset, watchdog timer reset, or oscillation stop detect reset are as follows:
- 00000000b when bits PM01 and PM00 in the PM0 register are 00b (single-chip mode).
- 00000010b when bits PM01 and PM00 in the PM0 register are 01b (memory expansion mode) or 11b (microprocessor mode).
