Exit Priority Register
b7 b6 b5 b4
When using an interrupt to exit wait mode or stop mode, refer to 9.5.2 Wait Mode and 9.5.3 Stop Mode for
details.
NOTES:
1. The MCU exits stop or wait mode when an interrupt priority level of a requested interrupt is higher than a level set using bits
2. Do not set both the FSIT and DMAII bits to 1.
3. Only one interrupt can have the interrupt priority level 7 when selecting the high-speed interrupt.
4. The DMAII bit is undefined after reset. To use interrupt priority level 7 for an interrupt, set it to 0 before setting the Interrupt
Set either the FSIT bit or the DMAII bit to 1 before setting bits ILVL2 to ILVL0 in the Interrupt Control Register to 111b.

RLVL2 to RLVL0. Set bits RLVL2 to RLVL0 to the same value as IPL in the FLG register.
