Table 27. Power Selection Summary
MCHG and MCHGBYP turn on fully to support the system
power requirements.
TURN ON EVENTS
previously to reach to the active state, can be obtained via a
turn on event. The turn on events are listed by the following.
To indicate to the SC, which turn on event caused the system
to power on, a corresponding interrupt status bit is set,
allowing the system controller to retrieve when it is up.
