Since the CPU clock stops in wait mode, the CPU, which operates using the CPU clock, and the watchdog
timer, when count source protection mode is disabled, stop. The XIN clock, XCIN clock, and on-chip oscillator
clock do not stop and 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 when the WAIT instruction is executed.
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.
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.
The I/O port is the status before wait mode was entered is maintained.
