The various special features of Port D are elaborated in
88.
AV
connected to V
through a low-pass filter. Note that PC6..4 use digital supply voltage, V
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.
CC
is the supply voltage pin for the A/D Converter, PC3:0, and ADC7:6. It should be externally
CC
, even if the ADC is not used. If the ADC is used, it should be connected to V
