9.7.2.4
C bus interface interrupt
The MCU exits wait mode by a reset or peripheral function interrupt.
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), the peripheral function interrupts other than A/D conversion
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 and the peripheral functions operating
with external signals or the on-chip oscillator clock can be used to exit wait mode.
Table 9.4 lists Interrupts to Exit Wait Mode and Usage Conditions.
