Analog-to-Digital Converter (A.D.C) reference.
The ADC reference (ADVREF) must be provided from an external source. Two decoupling
capacitors must be used to insure proper decoupling.
Refer to Section 38.4 on page 765 for decoupling capacitors values and electrical
characteristics.
In case ADC is not used, the ADVREF pin should be connected to GND to avoid extra
consumption.
