I/O
Port 3
is a bidirectional I/O port with internal pull-up resistors.
Port 3 pins that have 1s written to them are pulled high by
the internal pullup resistors, and in that state can be used
as inputs. As inputs, port 3 pins being externally pulled
low will source current (
I
IL
, in the DC characteristics)
because of the internal pullup resistors. Port 3 also
contains the interrupt, timer, serial port and external
memory strobe pins that are used by various options. The
output latch corresponding to a secondary function must
be programmed to a one (1) for that function to operate.
The secondary functions are assigned to the pins of port
3 as follows:

Counter 0 input
Counter 1 input
Write control signal : latches the data
byte from port 0 into the external
data memory
Read control signal : enables the
external data memory to port 0
