NOTE:
In applications that require V
enabling LVI resets allows the LVI module to reset the MCU when V
falls below the V
the LVIPWRD 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

The LVI5OR3 bit in the CONFIG1 register selects whether the LVI is
