lower than the IDLE2 mode. If the subclock oscillator, internal oscillator, and external clock are not used, the power
consumption can be minimized with only leakage current flowing.

time has been secured.
The STOP mode is set by setting the PSMR.PSM1 and PSMR.PSM0 bits to 01 or 11 and setting the PSC.STP bit
In the STOP mode, the subclock oscillator continues operating but the main clock oscillator stops. Clock supply to
As a result, program execution stops, and the contents of the internal RAM before the STOP mode was set are
Table 27-9 shows the operating status in the STOP mode.
Because the STOP mode stops operation of the main clock oscillator, it reduces the power consumption to a level
Cautions 1. Insert five or more NOP instructions after the instruction that stores data in the PSC register
The STOP mode is released by a non-maskable interrupt request signal (NMI pin input, INTWDT2 signal),
After the STOP mode has been released, the normal operation mode is restored after the oscillation stabilization
(1) Releasing STOP mode by non-maskable interrupt request signal or unmasked maskable interrupt
request signal
The STOP mode is released by a non-maskable interrupt request signal or an unmasked maskable interrupt
request signal, regardless of the priority of the interrupt request signal. If the STOP mode is set in an interrupt
servicing routine, however, an interrupt request signal that is issued later is serviced as follows.
(a) If an interrupt request signal with a priority lower than that of the interrupt request currently being serviced
(b) If an interrupt request signal with a priority higher than that of the interrupt request currently being serviced
