(for the option byte, see CHAPTER 17 OPTION BYTE).
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

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 34 s
(TYP.) (after an additional wait time for stabilizing the oscillation set by the oscillation
stabilization time select register (OSTS) has elapsed when crystal/ceramic oscillation is
used).
