Input This pin is a reference voltage input for the A/D converter.
Input/Output This is an 8-bit CMOS I/O port. It has an input/output port direction
register that allows the user to set each pin for input or output
individually. When used for input, a pull-up register option can be
selected for the entire group of four pins. Software can also select
this port to function as A/D converter input pins. P0
64 pin version.
Input/Output This is an 8-bit I/O port equivalent to P0. Additional software
selectable secondary functions are: 1) P1
converter input pins; 2) P1
interrupt pins; 3) P1
position-data-retain function input pins, and; 4) P1
trigger for the A/D converter. P1
