HARDWARE DESCRIPTION

Introduction

This chapter describes the board level hardware features of the MVME197DP
and MVME197SP versions of the MVME197 series of Single Board Computers,
hereafter referred to as the MVME197, unless separately specified (refer to the
next section for model designations).

The chapter is organized with a board level overview and features listed in this
introduction, followed by a more detailed hardware functional description.
Front panel switches and indicators are included in the detailed hardware
functional description. This chapter closes with some general memory maps.

All programmable registers used in the MVME197 module series reside in
ASIC (Application-Specific Integrated Circuit) devices that are covered in the

MVME197LE, MVME197DP, and MVME197SP Single Board Computers
Programmer’s Reference Guide

.
