I/O

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 Port 6 pins also serve for alternate functions:

I/O

Port 8 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 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.1)
