Port 9 is a 6-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 9 outputs can be configured as push/

pull or open drain drivers.

The following Port 9 pins also serve for alternate functions:1)
