Indicates the AUX powerdown state when AUX domain is powered
up.
0: Active mode
1: AUX Powerdown request has been granted
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.

Indicates AUX power state:
0: AUX is not ready for use ( may be powered off or in power state
transition )
1: AUX is powered on, connected to bus and ready for use,
Indicates MCU power state:
0: MCU Power sequencing is not yet finalized and MCU_AONIF
registers may not be reliable
1: MCU Power sequencing is finalized and all MCU_AONIF registers
are reliable
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
