IO

Port 3 is a 15-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 3 outputs can be configured as push/

pull or open drain drivers. The input threshold of Port 3 is

selectable (TTL or special).

The following Port 3 pins also serve for alternate functions:
