In this example the chip enters the software standby mode when
NMI
The NMI edge bit (NMIEG) in the system control register is originally cleared to 0, selecting the
falling edge. When
SSBY to 1 (selecting the rising edge), then executes the SLEEP instruction. The chip enters
software standby mode. It recovers from software standby mode on the next rising edge of
