NOTE:
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

The LVI5OR3 bit in the configuration register selects whether the LVI is
configured for 5-V or 3-V protection.
