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 CMOS). The following Port 3 pins have alternate functions:
