(2) Wait Mode
In wait mode, the CPU clock is turned off, so are the CPU (because operated by the CPU clock) and the
watchdog timer. Because the main clock and sub clock, are on, the peripheral functions using these
clocks keep operating.
Peripheral Function Clock Stop Function
If the CM02 bit is “1” (peripheral function clocks turned off during wait mode), the f1, f2, f8, f32, f1SIO,
f8SIO, f32SIO and fAD clocks are turned off when in wait mode, with the power consumption reduced
that much. However, fC32 remains on.
Entering Wait Mode
The microcomputer is placed into wait mode by executing the WAIT instruction.
Pin Status During Wait Mode
Table 2.5.2 lists pin status during wait mode
Exiting 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 “0002” (interrupts disabled) before execut-
ing the WAIT instruction.
The peripheral function interrupts are affected by the CM02 bit. If CM02 bit is “0” (peripheral function
clocks not turned off during wait mode), all peripheral function interrupts can be used to exit wait
mode. If CM02 bit is “1” (peripheral function clocks turned off during wait mode), the peripheral func-
tions using the peripheral function clocks stop operating, so that only the peripheral functions clocked
by external signals can be used to exit wait mode.
