NXP Semiconductors QorIQ LX2160A - Power Status 1 (PWR_STAT1)

3.28 Power Status 1 (PWR_STAT1)
Address
Register Offset
PWR_STAT1 025h
Function
The PWR_STATn registers are used to monitor the status of individual power supplies. If a bit is set to '1', the respective power
supply is operating correctly.
Note that unassigned bits default to one, allowing power failure detection to be easily performed (if the value is not FFh, at least
one supply is not operating).
Due to the high variability of the hardware devices used, PWR_STATn register bits are not assigned any universally fixed values.
For more details, see the target platform documentation.
