1. To use WKUP1 to exit power-off mode, set the POM03 bit to 1 (input enabled) by the initial write to the
2. To use timer RE to exit power-off mode, enable the timer RE interrupt in registers TREIC and TRECR2, then
To exit power-off mode, input a low signal pulse to the RESET, WKUP0, or WKUP1 pin or use the timer RE
interrupt (power-off 1 is selected). The timer RE interrupt enabled in the TREC2 register can be used to exit the
mode.
After exiting power-off mode, the operation is the same as a normal reset sequence.
When power-off mode is exited, the exit source can be identified by reading the flags in the SDCR0 register.
The values of these flags are undefined after power-on and set to 0 by writing to the SDCR0 register. If multiple
exit sources coincide, multiple flags are set.

set the POM00 bit in the POMCR0 register to 1 (timer RE enabled). When all interrupts are disabled by the
TRECR2 register, the low-speed clock and timer RE functions operate, but timer RE cannot be used to exit

The states of registers LSE0 to LSE7 before entering power-off mode are retained. When
LCD ports are selected by these registers, low-level output. When ports are selected, the
pins are placed in the high-impedance state.

All functions stop when the SDC00 bit is
set to 0 (power-off 0) by the initial write.
Functions other the low-speed clock and
timer RE stop when the SDC00 bit is set to
