AVCC is the supply voltage pin for the A/D Converter, Port C (3..0), and ADC (7..6). It should be

externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be con-

nected to VCC through a low-pass filter. Note that Port C (5..4) use digital supply voltage, VCC.

AREF is the analog reference pin for the A/D Converter.

In the TQFP and QFN/MLF package, ADC7..6 serve as analog inputs to the A/D converter.

These pins are powered from the analog supply and serve as 10-bit ADC channels.
