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 (TTL or special).
Port 4 can be used to output the segment address lines and
for serial interface lines:

External Memory Read Strobe. RD is activated for every
external instruction or data read access.
External Memory Write Strobe. In WR-mode this pin is
activated for every external data write access. In WRL-mode
this pin is activated for low byte data write accesses on a
16-bit bus, and for every data write access on an 8-bit bus.
See WRCFG in register SYSCON for mode selection.
