When the PM03 bit in the PM0 register is set to "1" (microcomputer reset), pins, the CPU and SFR are
reset. Then the microcomputer executes the program from an address determined by the reset vector.
When software reset is performed, some registers in the SFR are not reset. Refer to 4. SFR for details.
Set the PM03 bit to "1" while the main clock is selected as the CPU clock and the main clock oscillation is
stable.
The microcomputer resets pins, the CPU and the SFR when the watchdog timer underflows while the
CM06 bit in the CM0 register is set to "1" (reset). Then the microcomputer executes the program from an
address indicated by the reset vector.
When watchdog timer reset is performed, some registers in the SFR are not reset. Refer to 4. SFR for
details. Because the PM01 to PM00 bits in the PM0 register are not reset, the processor mode remains
unchanged.
