Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Power down acknowledgment. Indicates whether the power down
request given by PWRDWNREQ.REQ is captured by the AON
domain or not
0: AUX can assume that the system is in active mode
1: The request for power down is acknowledged and the AUX must
act like the system is in power down mode and power supply is
limited
The system CPU cannot use this bit since the bus bridge between
MCU domain and AUX domain is always disconnected when this bit
is set. For AUX_SCE use only.
