Port 2 is a 16-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 following Port 2 pins also serve for alternate functions:
CC0IO CAPCOM1: CC0 Capture Inp./Compare Output
CC1IO CAPCOM1: CC1 Capture Inp./Compare Output
CC2IO CAPCOM1: CC2 Capture Inp./Compare Output
