The following features support low power operation.
The system enters a low-power mode by execution of a STOP, WAIT, or
DOZE instruction.This idles the CPU with no cycles active. An internal
signal indicates to the system and clock controller to power down and
stop the clocks appropriately. During stop mode, the system clock is
stopped low.
A wakeup event is required to exit a low-power mode and return to run
mode. Wakeup events consist of any of these conditions:
Run mode is the normal system operating mode. Current consumption
in this mode is related directly to the system clock frequency.
