The STOP mode is set by executing the STOP instruction, and it can be set when the CPU clock before the
setting was the X1 input clock or Ring-OSC 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.

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.
