Ground.
Port A is a 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port A output buffers have symmetrical drive characteristics with both high sink and source
capability, except PA2 which has the RESET capability. To use pin PA2 as I/O pin, instead of
RESET pin, program (“0”) RSTDISBL fuse. As inputs, Port A pins that are externally pulled low
