Port C is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
PC5..0 output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port C pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
If the RSTDISBL Fuse is unprogrammed, PC6 is used as a Reset input. A low level on this pin
for longer than the minimum pulse length will generate a Reset, even if the clock is not run-
ning. The minimum pulse length is given in
guaranteed to generate a Reset.

Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
The Port D output buffers have symmetrical drive characteristics with both high sink and
source capability. As inputs, Port D pins that are externally pulled low will source current if the
pull-up resistors are activated. The Port D pins are tri-stated when a reset condition becomes
active, even if the clock is not running.

AREF is the analog reference pin for the A/D converter.
In the TQFP and QFN 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.
