The I/O port pins retain their status held just prior to wait mode.
The microcomputer is moved out of wait mode by a hardware reset, NMI interrupt or peripheral func-
tion interrupt.
If the microcomputer is to be moved out of exit wait mode by a hardware reset or NMI interrupt, set the
peripheral function interrupt priority ILVL2 to ILVL0 bits to “000
ing the WAIT instruction.
The peripheral function interrupts are affected by the CM02 bit. If CM02 bit is set to “0” (peripheral
function clocks not turned off during wait mode), peripheral function interrupts can be used to exit wait
mode. If CM02 bit is set to “1” (peripheral function clocks turned off during wait mode), the peripheral
functions using the peripheral function clocks stop operating, so that only the peripheral functions
clocked by external signals can be used to exit wait mode.
Table 7.4 lists the interrupts to exit wait mode.
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.
The CPU clock turned on when exiting wait mode by a peripheral function interrupt is the same CPU
clock that was on when the WAIT instruction was executed.
