19.4.4
Figure 19.1 shows an example in which software standby mode is entered at the fall of NMI and
exited at the rise of NMI.
With the NMI edge select bit (NMIEG) cleared to 0 in SYSCR (selecting the falling edge), an
NMI interrupt occurs. Next the NMIEG bit is set to 1 (selecting the rising edge) and the SSBY bit
is set to 1; then the SLEEP instruction is executed to enter software standby mode.
Software standby mode is exited at the next rising edge of the NMI signal.
19.4.5
The I/O ports retain their existing states in software standby mode. If a port is in the high output
state, its output current is not reduced.
