16-bit bidirectional I/O port, bit-wise programmable for input or output via
direction bits. Programming an I/O pin as input forces the corresponding
output driver to high impedance state. Port 2 outputs can be configured as
push/pull or open drain drivers. The input threshold of Port 2 is selectable
(TTL or special).
The following Port 2 pins have alternate functions:
P2.0

15-bit (P3.14 is missing) bidirectional I/O port, bit-wise programmable for
input or output via direction bits. Programming an I/O pin as input forces
the corresponding output driver to high impedance state. Port 3 outputs
can be configured as push/pull or open drain drivers. The input threshold
of Port 3 is selectable (TTL or special).

8-bit bidirectional I/O port, bit-wise programmable for input or output via
direction bits. Programming an I/O pin as input forces the corresponding
output driver to high impedance state. For external bus configuration,
Port 4 can be used to output the segment address lines:
