Function
Port 8 is a 4-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. Port 8 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 8 is
selectable (TTL or special). Port 8 pins provide inputs/
outputs for CAPCOM2 and serial interface lines.
