All functions stop in power-off mode. However, the low-speed clock and timer RE functions can be set to operate
or stop by means of register settings. The least power is consumed in this mode.
Input a hardware reset as reset input.
For details of resets, refer to 5.2 Hardware Reset.
Figure 9.5 shows Pin Handling in Power-Off Mode. To use this mode, hardware reset input is required. For
details of hardware resets, refer to 5.2 Hardware Reset.
Table 9.5 lists the register settings in power-off mode.
The pin status in power-off mode and the method of exiting are selected by the initial write to the POMCR0
register. When 88h, 15h, 92h, and 25h are then written successively, the MCU enters power-off mode.

An access to another register during the write to the POMCR0 register does not affect entering the mode.
Table 9.6 lists the Pin Status in Power-Off Mode. When the MCU enters power-off mode, the contents of RAM
and registers are not retained. Save the data needs to be retained to the data flash before entering power-off
mode.
Power-off 0
When the POM00 bit is set to 0 (power-off 0) by the initial write, all functions stop once the MCU enters
power-off mode.
Power-off 1
When the POM00 bit is set to 1 (power-off 1) by the initial write, all functions except the low-speed clock and
timer RE stop once the MCU enters power-off mode. The timer RE interrupt can be used to exit the mode
when power-off 1 is selected.
Power-Off Mode
(1) When power-off mode is used
Always pull up WKUP0.
Pull up WKUP1 when selected as the exit source.
Input a low-level signal to exit the mode.
