(LVISR)
An LVI reset also drives the RST pin low to provide low-voltage
protection to external peripheral devices.
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.
