The STOP mode is set by executing the STOP instruction.
Caution Because an 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, in the STOP mode, the normal operation mode is
restored after the STOP instruction is executed and then the operation is stopped for the
duration of 34 s (TYP.) (after an additional wait time for stabilizing oscillation set by the
oscillation stabilization time select register (OSTS) has elapsed when crystal/ceramic
oscillation is used).
