Port 4 is an 8-bit bidirectional I/O port. Each pin can be
programmed for input (output driver in high-impedance
state) or output (configurable as push/pull or open drain
driver). 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:¹⁾
