Port A is a 4-bit bi-directional I/O port with internal pull-up resistors (selected for each bit) in
32-lead TQFP and 32-pad QFN package. The PA3..0 output buffers have symmetrical drive
characteristics with both high sink and source capability. As inputs, Port A pins that are exter-
nally pulled low will source current if the pull-up resistors are activated. The Port A pins are
tri-stated when a reset condition becomes active, even if the clock is not running.
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Depending on the clock selection fuse settings, PB6 can be used as input to the internal clock
operating circuit.
The various special features of Port B are elaborated in

Port C is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
PC7 and 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 programmed, PC6 is used as an Input pin.
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 width will generate a reset, even if the clock is not running. The
minimum pulse length is given in
generate a reset.
The various special features of Port C are elaborated in
