NOTES:

1. It is recommended to power AVCC and DVCC from the same source. A maximum difference of 0.3 V between AVCC and DVCC 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.
