In applications that can operate at V
software can monitor V
register, the LVIPWRD bit must be at logic 0 to enable the LVI module,
and the LVIRSTD bit must be at logic 1 to disable LVI resets.
In applications that require V
enabling LVI resets allows the LVI module to reset the MCU when V
falls below the V
and LVIRSTD bits must be at logic 0 to enable the LVI module and to
enable LVI resets.
Once the LVI has triggered (by having V
