M16C/62P Group, R32C/111 Group

Differences between M16C/62P and R32C/111 (100 pin ver.)

4.2 Resets

Hardware reset 1, low voltage detection (hardware reset 2), software reset, watchdog timer reset, and

oscillation stop detection reset are implemented to reset the MCU. However, the low voltage detection

and oscillation stop detection reset are available only in the M16C/62P.

Some SFRs remain uninitialized even after a reset operation.

Table 4.7 to Table 4.9 list the changes from the M16C/62P on reset operations.
