Note 1. All voltages with respect to ground.
Note 2. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 3. Max is smaller value between (AVDD+0.3) and 4.6V.
Note 4. Max is smaller value between (DVDD+0.3) and 4.6V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
