Unimplemented.

Write 0. Read as undefined value.

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

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

2. Do not set both the FSIT and DMAII bits to 1.

Set either the FSIT bit or the DMAII bit to 1 before setting bits ILVL2 to ILVL0 in the Interrupt Control Register to 111b.

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

Control Register.
