8-bit bidirectional I/O port, bit-wise programmable for input or output via direction
bit. Programming an I/O pin as input forces the corresponding output driver to
high impedance state. Port 7 outputs can be configured as push-pull or open
drain drivers. The input threshold of Port 7 is selectable (TTL or CMOS).
The following Port 7 pins have alternate functions:

P7.7
16-bit input-only port with Schmitt-Trigger characteristics. The pins of Port 5 can
be the analog input channels (up to 16) for the A/D converter, where P5.x equals
ANx (Analog input channel x), or they are timer inputs. The input threshold of
Port 5 is selectable (TTL or CMOS). The following Port 5 pins have alternate
functions:

16-bit bidirectional I/O port, bit-wise programmable for input or output via
direction bit. Programming an I/O pin as input forces the corresponding output
driver to 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 CMOS).
