generate a reset.
The various special features of Port C are elaborated in
72.
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
PD[7:4] output buffers have symmetrical drive characteristics with both sink and source capabil-
ities, while the PD[3:0] output buffers have high sink capabilities. 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.
The various special features of Port D are elaborated in
75.
