Since the CPU clock stops in wait mode, the CPU operating with the CPU clock and the watchdog timer when
count source protection mode is disabled stop. Since the XIN clock, XCIN clock, and on-chip oscillator clock
do not stop, the peripheral functions using these clocks continue operating.
If the CM02 bit is set to 1 (peripheral function clock stops in wait mode), the f1, f2, f4, f8, and f32 clocks stop
in wait mode. This reduces power consumption.
The MCU enters wait mode by executing the WAIT instruction or setting the CM30 bit in the CM3 register to 1
(MCU enters wait mode).
When the OCD2 bit in the OCD register is set to 1 (on-chip oscillator selected as system clock), set the OCD1
bit in the OCD register to 0 (oscillation stop detection interrupt disabled) before executing the WAIT
instruction or setting the CM30 bit in the CM3 register to 1(MCU enters wait mode).
If the MCU enters wait mode while the OCD1 bit is set to 1 (oscillation stop detection interrupt enabled),
current consumption is not reduced because the CPU clock does not stop.
Enter wait mode after setting the FMR27 bit to 0 (low-current-consumption read mode disabled). Do not enter
wait mode while the FMR27 bit is 1 (low-current-consumption read mode enabled).
The I/O port retains the status immediately before the MCU enters wait mode.
