Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this datasheet. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
2. The datasheet limits are not guaranteed if the device exceeds the operating ratings.
3. Crystal input is powered from VDDI_2 analog supply voltage source.
