PARAMETER
Specifications to 0°C are guaranteed by design and are not production tested.
It is not recommended to write to flash memory when the supply voltage drops below the power-fail warning levels as
there is uncertainty in the duration of continuous power supply. The user application should check the status of the power-
fail warning flag before writing to flash to ensure complete write operations.
The power-fail warning monitor and the power-fail reset monitor track each other with a minimum delta between the two of
0.11V.
The power-fail reset and power-on-reset (POR) detectors operate in tandem to ensure that one or both signals are active
