Function
Port 4 is an 8-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state. The Port 4 outputs can be configured as
push/pull or open drain drivers. The input threshold of Port 4
is selectable (standard or special).
Port 4 can be used to output the segment address lines, the
optional chip select lines, and for serial interface lines:
