C.1 Introduction

The DIO connector on the PPC-51xxA-G41/WIDS-51xA-G41 is interfaced to GPIO ports

on the Super I/O chipset. The DIO has both 4-bit digital inputs and 4-bit digital outputs.

The digital inputs and digital outputs are generally control signals that control the on/off

circuit of external devices or TTL devices. Data can be read or written to the selected

address to enable the DIO functions.

NOTE:

For further information, please refer to the datasheet for the Super I/O

chipset.
