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:

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. 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
