The following pins receive their supply voltage from AV
ages) PA[1:0]. All other I/O pins take their supply voltage from V
Ground.
Port A is a 4-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
PA[3:0] output buffers have symmetrical drive characteristics with both sink and source capabil-
ity. As inputs, Port A pins that are externally 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.
This port is available in 32-lead TQFP, 32-pad QFN and 32-ball UFBGA packages, only.
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 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
69.
Port C is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
PC7 and PC[5:0] output buffers have symmetrical drive characteristics with both 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 I/O pin. Note that the electrical char-
acteristics of PC6 differ from those of the other pins of Port C.
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
