Port 5 is a 16-bit input-only port with Schmitt-Trigger
characteristics. The pins of Port 5 also serve as the (up to 16)
analog input channels for the A/D converter, where P5.x
equals ANx (Analog input channel x), or they serve as timer
inputs:

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:
