1. The maximum difference in the voltage of AVDD, DACVDD, ADCVDD, analog inputs and analog outputs
must not exceed 0.5V. Warning: Operation at or beyond these limits may result in permanent damage to
the device. Normal operation is not guaranteed at these extremes.
2. During Normal Mode operation VDD3 is always available as specified.
3. During Fail-save Mode operation VDD3 may be not available.
