8-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 6 outputs can be configured as push-pull or open
drain drivers. The input threshold of Port 6 is selectable (TTL or CMOS). The
following Port 6 pins have alternate functions:
