M16C/62P Group, R32C/111 Group

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

4.5 Processor Modes

Table 4.12 lists the changes on SFRs associated with processor mode.

4.6 Clocks

Table 4.13 to Table 4.17 respectively list the changes on clock characteristics, settings, and associated

SFRs.

Note:

1. “low-speed mode” and “low power dissipation mode” are used in M16C/62P. These words are

respectively changed to “low speed mode” and “low power mode” in R32C/111.
