This pin is a reference voltage input for the A-D converter.
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 set for input, the user can specify in units of four
bits via software whether or not they are tied to a pull-up resistor.
This is an 8-bit I/O port equivalent to P0.
This is an 8-bit I/O port equivalent to P0.
This is an 4-bit I/O port equivalent to P0.
This is an 8-bit I/O port equivalent to P0. In single-chip mode, P5
this port outputs a divide-by-8 or divide-by-32 clock of X

This is an 4-bit I/O port equivalent to P0 (P7
open-drain output). Pins in this port also function as timer A

NMI function cannot be cancelled using software. The pull-up cannot be
set for this pin.
This is an 8-bit I/O port equivalent to P0. Pins in this port also function
as UART0 and UART1 I/O pins as selected by software.
