To enter power-off mode, set the FMR01 bit in the FMR0 register to 0 (CPU rewrite mode disabled) and then
access the POMCR0 register. A period of a few microseconds is required between accessing the POMCR0
register and entering power-off mode. As the CPU continues to operate during this period, insert the NOP and
the WAIT instructions to stop the program.
•
The operation after power-off mode is exited is the same as a normal reset sequence. When power-off mode is
exited immediately after the MCU enters the mode, therefore, power consumption cannot be reduced because
of the reset sequence and the program operation after a reset. Evaluate the interval between entering and exiting
power-off mode fully at the system level.
Write 00h to the POMCR0 register (address 0020h).
The power supply current may increase until 00h is written to this register.
Program example: MOV.B #00H, 0020H
