5. STANDBY FUNCTION
There are the following two standby functions to reduce the system power consumption.
HALT mode : The CPU operating clock is stopped.
The average consumption current can be reduced by intermittent operation in combination with
the normal operating mode.
STOP mode : The system clock oscillation is stopped. All operations by the system clock are stopped and
current consumption can be considerably reduced.
