than interrupts IRQ7 to IRQ0 is generated. Software standby mode cannot be cleared if the
interrupt has been masked on the CPU side or has been designated as a DTC activation source.
When the RES pin or MRES pin is driven low, clock oscillation is started. At the same time as
clock oscillation starts, clocks are supplied to the entire this LSI chip. Note that the RES pin or
MRES pin must be held low until clock oscillation settles. When the RES pin or MRES pin
goes high, the CPU begins reset exception handling.
When the STBY pin is driven low, a transition is made to hardware standby mode.
Set bits STS2 to STS0 so that the standby time is at least tOSC2 ms (the oscillation settling
time). Table 24.3 shows the standby times for different operating frequencies and settings of
bits STS2 to STS0.
Any value can be set. Normally, minimum time is recommended.
