resistors are activated. The Port D pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

The various special features of Port D are elaborated in “Alternate functions of port D” on page

AVCC

AREF

AVCC is the supply voltage pin for the A/D Converter, PC3:0, and ADC7:6. It should be externally

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

through a low-pass filter. Note that PC6..4 use digital supply voltage, VCC.

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

ADC7:6 (TQFP and QFN/MLF package only)

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.
