PRG: CTRL_MMR STAT registers are unreliable indicators of POK threshold failure

Details

The POK overvoltage and undervoltage flags in the CTRL_MMR PRG STAT registers are unreliable indicators of whether the POK has seen a failure. As a result, they are being marked as Reserved in the device Technical Reference Manual (TRM).

Workaround

The filtered POK output updates ESM flags.

Upon POK initialization (i.e. enable), the ESM flags should be cleared (due to comparisons carried out during the bandgap and / or the POK settling time). After this initial clear, the ESM flags can be used as a reliable indicator of failure (or no failure) from the POKs.
