10.4.2.4
The MCU exits wait mode by a hardware reset or a peripheral function interrupt. To use a hardware reset to exit
wait mode, set bits ILVL2 to ILVL0 for the peripheral function interrupts to 000b (interrupts disabled) before
executing the WAIT instruction.
The peripheral function interrupts are affected by the CM02 bit. When the CM02 bit is set to 0 (peripheral
function clock does not stop in wait mode), all peripheral function interrupts can be used to exit wait mode.
When the CM02 bit is set to 1 (peripheral function clock stops in wait mode), the peripheral functions using the
peripheral function clock stop operating and the peripheral functions operated by external signals can be used to
exit wait mode.
Table 10.3 lists Interrupts to Exit Wait Mode and Usage Conditions.
