10.4.4

Exiting Wait Mode

The MCU exits wait mode by a reset or peripheral function interrupt. The peripheral function interrupts are

affected by bits CM01 and CM02.

The following interrupts can be used to exit wait mode:

• When bits CM02 to CM01 are set to 00b (peripheral function clock does not stop in wait mode), peripheral

function interrupts other than A/D conversion interrupts.

• When bits CM02 to CM01 are set to 01b (clocks f1 to f32 stop in wait mode), the interrupts of the peripheral

functions operating with external signals, the on-chip oscillator clock, or clocks fC1 to f32.

• When bits CM02 to CM01 are set to 10b (clocks f1 to f32 and fC stop in wait mode), the interrupts of the

peripheral functions operating with external signals or the on-chip oscillator clock.

• When bits CM02 to CM01 are set to 11b (clocks f1 to f32, fC, and fC-LCD stop in wait mode), the same

applies when bits CM02 to CM01 are set to 10b.

Table 10.3 lists Interrupts to Exit Wait Mode and Usage Conditions.
