External Power Supply Failure Mode
These commands allow configuring the behavior of the G25A upon assertion of an
external power supply fail signal.
Modes:
Ignore: Assertion of external power failure signal is completely ignored.
Treat as error: Assertion of external power failure is treated as an error; i.e. event is
counted as an error and G25A is reset.
The setting is persistent, i.e. it is stored in non-volatile memory.
The default external power supply fail signal mode after factory programming is
"Ignore".
