9.4.2.4
The microcomputer exits wait mode by a hardware reset or peripheral function interrupt. When using
a hardware reset to exit wait mode, set the ILVL2 to ILVL0 bits 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 9.3 lists Interrupts to Exit Wait Mode and Usage Conditions.
When using a peripheral function interrupt to exit wait mode, set up the following before executing
the WAIT instruction.
When an interrupt request is generated and the CPU clock supply is started if exiting by the
peripheral function interrupt, an interrupt sequence is executed.
The CPU clock, when exiting wait mode by a peripheral function interrupt, is the same clock as the
CPU clock when the WAIT instruction is executed.
(1) Set the interrupt priority level to the ILVL2 to ILVL0 bits in the interrupt control register of the
(2) Set the I flag to “1”.
(3) Operate the peripheral functions to use for exiting wait mode.

peripheral function interrupts to use for exiting wait mode. Set the ILVL2 to ILVL0 bits of the
peripheral function interrupts not to use for exiting wait mode to “000b” (disables interrupt).
