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: CS0 Chip Select 0 Output CS1 Chip Select 1 Output CS2 Chip Select 2 Output CS3 Chip Select 3 Output CS4 Chip Select 4 Output SDA1 I 2C Bus Data Line 1 SCL1 I 2C Bus Clock Line 1 SDA2 I 2C Bus Data Line 2 Note: Pins P6.7-5 are open drain outputs only.

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. The input threshold of Port 2 is selectable (TTL or special). The Port 2 pins also serve for alternate functions: EX0IN Fast External Interrupt 0 Input EX1IN Fast External Interrupt 1 Input EX2IN Fast External Interrupt 2 Input EX3IN Fast External Interrupt 3 Input EX4IN Fast External Interrupt 4 Input EX5IN Fast External Interrupt 5 Input EX6IN Fast External Interrupt 6 Input EX7IN Fast External Interrupt 7 Input 9 AREF 95 97 - Reference voltage for the A/D converter. 9 AGND 96 98 - Reference ground for the A/D converter.
