Port 3:
Port 3 is an 8-bit bidirectional I/O port with internal
pullups. Port 3 pins that have 1s written to them are pulled high
by the internal pullups and can be used as inputs. As inputs, Port
3 pins that are externally pulled low will source current because
of the internal pullups. (See DC Characteristics: I
IL
).
Port 3 also serves the special features of the IC80C52, as listed

Program Store Enable:
The read strobe to external program
memory. When the device is executing code from the external
program memory,
PSEN
is activated twice each machine cycle
except that two
PSEN
activations are skipped during each
access to external data memory.
PSEN
is not activated during
fetches from internal program memory.

Reset:
A high on this pin for two machine cycles while the
oscillator is running, resets the device. An internal MOS resistor
to GND permits a power-on reset using only an external capaci-
tor connected to Vcc.
