P3.0 to P3.7
I/O with
internal
pull-up
Port 3: Port 3 is an 8-bit bidirectional I/O port with internal
pull-ups. Port 3 pins are pulled HIGH by the internal
pull-ups when ‘1’s are written to them and can be used as
inputs in this state. As inputs, Port 3 pins that are
externally pulled LOW will source current (IIL) because of
the internal pull-ups. Port 3 also receives some control
signals and a partial of high-order address bits during the
external host mode programming and verication.

I/O
Program Store Enable: PSEN is the read strobe for
external program memory. When the device is executing
from internal program memory, PSEN is inactive (HIGH).
When the device is executing code from external program
memory, PSEN is activated twice each machine cycle,
except that two PSEN activations are skipped during each
access to external data memory. A forced HIGH-to-LOW
input transition on the PSEN pin while the RST input is
continually held HIGH for more than 10 machine cycles will
cause the device to enter external host mode
programming.
