NOTES: 1. It is recommended to power AV
CC
and DV
CC
from the same source. A maximum difference of 0.3 V between AV
CC
and DV
CC
can
be tolerated during power up and operation.
2. The minimum operating supply voltage is defined according to the trip point where POR is going active by decreasing the supply
voltage. POR is going inactive when the supply voltage is raised above the minimum supply voltage plus the hysteresis of the SVS
circuitry.
3. In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.
