If the microcomputer is to be moved out of wait mode by a peripheral function interrupt, set up the
following before executing the WAIT instruction.
(1) Set the ILVL2 to ILVL0 bits in the interrupt control register, for peripheral function interrupts used to
exit wait mode.
The ILVL2 to ILVL0 bits in all other interrupt control registers, for peripheral function interrupts not
used to exit wait mode, are set to “000b” (interrupt disable).
(2) Set the I flag to “1”.
(3) Start operating the peripheral functions used to exit wait mode.
When the peripheral function interrupt is used, an interrupt routine is performed as soon as an
interrupt request is acknowledged and the CPU clock is supplied again.
When the microcomputer exits wait mode by the peripheral function interrupt, the CPU clock is the same
clock as the CPU clock executing the WAIT instruction.
