Function
Port 6 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. Port 6 outputs can be configured as push/
pull or open drain drivers.
The following Port 6 pins also serve for alternate functions:

Port 2 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. Port 2 outputs can be configured as push/
pull or open drain drivers.
