19.2. Power-Fail Reset/V
When a power-down transition or power irregularity causes V

memory contents are not altered by the power-fail reset, it is impossible to determine if V
the level required for data retention. If the PORSF flag reads 1, the data may no longer be valid. The V
monitor is enabled after power-on resets. Its defined state (enabled/disabled) is not altered by any other
reset source. For example, if the V

in the application, a delay should be introduced between enabling the monitor and selecting it as a reset
source. The procedure for enabling the V
state is shown below:
