22.4.4
Figure 22.3 shows an example in which a transition is made to software standby mode at the
falling edge on the NMI pin, and software standby mode is cleared at the rising edge on the NMI
pin.
In this example, an NMI interrupt is accepted with the NMIEG bit in SYSCR cleared to 0 (falling
edge specification), then the NMIEG bit is set to 1 (rising edge specification), the SSBY bit is set
to 1, and a SLEEP instruction is executed, causing a transition to software standby mode.
Software standby mode is then cleared at the rising edge on the NMI pin.
Set bits STS2 to STS0 so that the standby time is at least 8 ms (the oscillation settling time).
Table 22.3 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.
