Table 9.7 lists pin states in wait mode.
Wait mode is exited by the hardware reset, NMI interrupt or peripheral function interrupts.
When the hardware reset or NMI interrupt, but not the peripheral function interrupts, is used to exit wait
mode, set the ILVL2 to ILVL0 bits for the peripheral function interrupts to "000
before executing the WAIT instruction.
CM02 bit setting affects the peripheral function interrupts. When the CM02 bit in the CM0 register 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), peripheral functions using the peripheral function clock stop. Therefore, the peripheral function
interrupts cannot be used to exit wait mode. However, the peripheral function interrupts caused by an
external clock, f
to exit wait mode.
The CPU clock used when exiting wait mode by the peripheral function interrupts or NMI interrupt is
the same CPU clock used when the WAIT instruction is executed.
Table 9.8 shows interrupts to be used to exit wait mode and usage conditions.
