9 / 49 page C165 Semiconductor Group 8 P6.0 – P6.7 84 - 91 84 ... 88 89 90 91 I/O O ... O I O 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 following Port 6 pins also serve for alternate functions: P6.0 CS0 Chip Select 0 Output ... ... ...
