2. Electrical Characteristics

Note 1.

Use AVCC0 and VCC under the following conditions:

AVCC0 and VCC can be set individually within the operating range when VCC ≥ 2.0 V

AVCC0 = VCC when VCC < 2.0 V

Note 2.

When powering on the VCC and AVCC0 pins, power them on at the same time or the VCC pin first and then the AVCC0 pin.
