3.28.2 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.
