1. VDD3 refers to all of the nominal 3.3V power supplies (VDDH, VOSC, VDDSD). VDD refers to all of the nominal

1.8V power supplies (VDD, VMTR).

2. During Normal Mode operation VDD3 is always available as specified.

3. During Fail-safe Mode operation VDD3 may be not available.

Warning: Operation at or beyond these limits may result in permanent

damage to the device. Normal operation is not guaranteed at

these extremes.
