The STOP mode is set by executing the STOP instruction, and it can be set regardless of whether the CPU clock
before the setting was the high-speed system clock or internal low-speed oscillation clock.
Caution Because the interrupt request signal is used to clear the standby mode, if there is an interrupt
The operating statuses in the STOP mode are shown below.

When “Stopped by software” is selected for internal low-speed oscillator by an option byte and internal low-

“Internal low-speed oscillator cannot be stopped” or “Internal low-speed oscillator can be stopped by
software” can be selected by an option byte.
source with the interrupt request flag set and the interrupt mask flag reset, the standby mode is
immediately cleared if set. Thus, the STOP mode is reset to the HALT mode immediately after
execution of the STOP instruction and the system returns to the operating mode as soon as the
wait time set using the oscillation stabilization time select register (OSTS) has elapsed.
