Port 0-I/O - AD0-7.
Port 0 is an open-drain 8-bit, bi-directional general-purpose
I/O port. When used in this mode pullup resistors are required to provide a logic 1
output. As an alternate function, Port 0 operates as a multiplexed address/data bus
to access off-chip memory or peripherals. In this mode, the LSB of the memory
address is output on the bus during the time that ALE is high. When ALE falls to
a logic 0, the port transitions to a bi-directional data bus. In this mode, the port
provides active high drivers for logic 1 output. The reset condition of Port 0 is tri-
state (i.e., the open drain devices are off).

Port 2-I/O Address A15:A8.
Port 2 functions as an 8-bit bi-directional I/O port
or alternately as an external address bus (A15-A8). The reset condition of Port 2 is
logic high I/O state. In this state, weak pullups hold the port high allowing the
pins to be used as an input or output as described above for Port 1. As an alternate
function Port 2 can function as MSB of the external address bus. This bus can be
used to read external memory or peripherals.
Port 3 - I/O.
Port 3 functions as an 8-bit bi-directional I/O port or alternately as
an interface for External Interrupts, Serial Port 0, Timer 0 & 1 Inputs, and
RD
and
WR
strobes. When functioning as an I/O port, these pins operate as indicated
above for Port 1. The alternate modes of Port 3 are detailed below.

Port 4 - I/O.
Port 4 functions as an 8-bit bi-directional I/O port or alternately as
an interface to Timer 2’s Capture Compare functions. When functioning as an I/O
port, these pins operate as indicated in the Port 1 description. The alternate modes
of Port 4 are detailed below.
