Programmable power consumption
3 V or 5 V selectable trip point
Setting the LVI power disable bit, LVIPWRD, disables the LVI.
Setting the LVI reset disable bit, LVIRSTD, prevents the LVI module from generating a reset.
Setting the LVI enable in stop mode bit, LVISTOP, enables the LVI to continue monitoring the
