Figure 23.2 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, after an NMI interrupt is accepted with the NMIEG bit in INTCR cleared to 0
(falling edge specification), the NMIEG bit is set to 1 (rising edge specification). And after the
SSBY bit is set to 1, 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.
