16-bit bidirectional I/O port, bit-wise programmable for input or output via direction
bit. 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:

15-bit (P3.14 is missing) bidirectional I/O port, bit-wise programmable for input or
output via direction bit. 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).
