NOTES: 1. The minimum operating supply voltage is defined according to the trip point where POR is going active by decreasing supply voltage.
POR is going inactive when the supply voltage is raised above minimum supply voltage plus the hysteresis of the SVS circuitry.
2. In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.
