Section 7. Input/Output (I/O) Ports
7.1 Contents
7.2 Introduction
In user mode, 20 bidirectional input/output (I/O) lines are arranged as:
Two 8-bit I/O ports, port A and port C
One 3-bit I/O port, port B
One 1-bit I/O port, port D
These ports are programmable as either inputs or outputs under
software control of the data direction registers (DDRs). There is also an
input-only pin associated with port D.
