Table 9.7 lists pin states in wait mode.
Wait mode is exited by the hardware reset 1, hardware reset 2, NMI interrupt, Vdet4 detection interrupt, or
peripheral function interrupts.
As for a peripheral function interrupt that is not used to exit wait mode, set bits ILVL2 to ILVL0 in the
corresponding Interrupt Control Register to 000b (interrupt disabled) before executing the WAIT instruction.
The CM02 bit setting in the CM0 register affects the use of the peripheral function interrupts to exit wait mode.
When the CM02 bit is set to 0 (peripheral clocks do not stop in wait mode), any peripheral function interrupts
can be used to exit wait mode. When the CM02 bit is set to 1 (peripheral clocks stop in wait mode), the
peripheral functions clocked by the peripheral function clocks stop, and therefore, the peripheral function
interrupts cannot be used to exit wait mode. However, the peripheral functions clocked by the external clock
and fC32 do not stop regardless of the CM02 bit setting. Also, f2n, which uses the XIN clock (fXIND) or on-
chip oscillator clock as its clock source does not stop. The interrupts generated by the peripheral functions
which operate using these clocks can be used to exit wait mode.
When the MCU exits wait mode by the peripheral function interrupts or NMI interrupt, the CPU clock does not
change before and after the WAIT instruction is executed.
Table 9.8 lists interrupts to be used to exit wait mode and usage conditions.
