25.3.3
This example describes a transition to software standby mode on the falling edge of the NMI
signal, and cancellation on the rising edge of the NMI signal. The timing is shown in figure 25.1.
When the NMI pin is changed from high to low level while the NMI edge select bit (NMIE) in
ICR is set to 0 (falling edge detection), the NMI interrupt is accepted. When the NMIE bit is set to
1 (rising edge detection) by the NMI exception service routine, the STBY and DEEP bits in
STBCR are set to 1 and 0 respectively, and a SLEEP instruction is executed, software standby
mode is entered. Thereafter, software standby mode is canceled when the NMI pin is changed
from low to high level.
