Port 7 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 7 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 7 is
selectable (TTL or special).
The following Port 7 pins also serve for alternate functions:

Port 5 is a 16-bit input-only port with Schmitt-Trigger
characteristic.
The pins of Port 5 also serve as analog input channels for the
A/D converter, or they serve as timer inputs:
