This section describes the low-voltage inhibit module, which monitors
the voltage on the V
falls to the LVI trip voltage.
Note that the LVI feature is intended to provide the safe shutdown
of the microcontroller and thus protection of related circuitry prior
to any application V
level. Is is not intended that users operate the microcontroller at
lower than the specified operating voltage, V
