Since the CPU clock stops in wait mode, CPU operation using the CPU clock and watchdog timer operation with
count source protection mode disabled are halted. However, the XIN clock, XCIN clock, and on-chip oscillator
clock do not stop, so peripheral functions using these clocks continue operating.
The peripheral function clock to stop in wait mode can be selected by setting bits CM01 and CM02 in the CM0
register (peripheral function clock stop bits in wait mode). This controls power consumption according to
applications.
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.
Each I/O port retains its states immediately before the MCU enters wait mode.
