Pins, the CPU and SFR are reset when the PM03 bit in the PM0 register is set to "1" (microcomputer reset).
Then the microcomputer executes the program in an address determined by the reset vector.
Set the PM03 bit to "1" while the main clock is selected as the CPU clock and the main clock oscillation is
stable.
In the software reset, the microcomputer does not reset a part of the SFR. Refer to 4. SFR for details.
Processor mode remains unchanged since the PM01 and PM00 bits in the PM0 register are not reset.
Pins, the CPU and SFR are reset when the CM06 bit in the CM0 register is set to "1" (reset) and the
watchdog timer underflows. Then the microcomputer executes the program in an address determined by
the reset vector.
In the watchdog timer reset, the microcomputer does not reset a part of the SFR. Refer to 4. SFR for details.
Processor mode remains unchanged since the PM01 and PM00 bits in the PM0 register are not reset.
