Section 7. Parallel Input/Output (I/O)
7.1 Contents
7.2 Introduction
This section describes the two bidirectional input/output (I/O) ports.
7.3 I/O Port Function
The 14 bidirectional I/O pins form two parallel I/O ports. Each I/O pin is
programmable as an input or an output. The contents of the data
direction registers determine the data direction of each I/O pin.
All 14 I/O pins have mask-optional, software-programmable pulldown
devices.
