10.5.2.4
C bus interface interrupt
1. For N, D version only.
The MCU exits wait mode by a reset or a 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), 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 or on-chip
oscillator clock can be used to exit wait mode.
Table 10.3 lists Interrupts to Exit Wait Mode and Usage Conditions.
