Preface
The MVME2400-Series VME Processor Module Installation and Usemanual provides the
information you will need to install and use your MVME2400-series VME processor
module (hereafter refered to as “MVME2400x” or “module”). The module is based on an
MPC750 PowerPC microprocessor, and features dual PCI Mezzanine Card (PMC) slots
with front panel and/or P2 I/O. The module is currently available in the configurations
listed in Chapter 1.
The MVME2400 is compatible with the optional double-width or single-width PCI
Mezzanine Cards (PMCs and with the PMCspan PCI expansion mezzanine module. By
utilizing the two onboard PMC slots and stacking the PMCspan(s), the MVME2400x
provides support for up to six PMCs.
This manual includes hardware preparation and installation instructions, along with
information on: using the front panel, programming the board, using the PPCBug
debugging firmware, and other advanced debugger topics. Appendices provide the
module’s specifications and connector pin assignments. Additional manuals you may wish
to obtain are listed in Appendix A.
The information in this manual applies principally to the MVME240x. The PMCspan and
PMCs are described briefly; however, they are documented in separate publications,
furnished with those products. Refer to the individual product documentation for complete
preparation and installation instructions. These manuals are listed in Appendix A.
This manual is intended for anyone who wants to design OEM systems, supply additional
capability to an existing compatible system, or work in a lab environment for experimental
purposes. A basic knowledge of computers and digital logic is assumed.

Conventions Used in This Manual
The following typographical conventions are used in this document:
bold
Is used for user input that you type just as it appears; it is also used for commands,
options and arguments to commands, and names of programs, directories and files.
italic
Is used for names of variables to which you assign values. Italic is also used for
comments in screen displays and examples, and to introduce new terms.
courier
Is usedfor system output (for example, screen displays, reports), examples, and system
prompts.
<Enter>, <Return> or <CR>
Represents the carriage return or Enter key.
CTRL
Represents the Control key. Execute control characters by pressing the Ctrl key and the
letter simultaneously, for example, Ctrl-d.
|
Separates two or more items that you can select from (one only).
[ ]
Encloses an optional item that may occur zero or one time.
{ }
Encloses an optional item that may occur zero or more times.

Terminology
A character precedes a data or address parameter to specify the numeric format, as follows
(if not specified, the format is hexadecimal):
An asterisk (*) following a signal name for signals that are level significant denotes that the
signal is true or valid when the signal is low.
An asterisk (*) following a signal name for signals that are edge significant denotes that the
actions initiated by that signal occur on high to low transition.
In this manual, assertion and negation are used to specify forcing a signal to a particular
state. In particular, assertion and assert refer to a signal that is active or true; negation and
negate indicate a signal that is inactive or false. These terms are used independently of the
voltage level (high or low) that they represent.
Data and address sizes are defined as follows:

Safety Summary
The following general safety precautions must be observed during all phases of operation, service, and repair of this
equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety
standards of design, manufacture, and intended use of the equipment. Motorola, Inc. assumes no liability for the
customer’s failure to comply with these requirements.
The safety precautions listed below represent warnings of certain dangers of which Motorola is aware. You, as the
user of the product, should follow these warnings and all other safety precautions necessary for the safe operation of
the equipment in your operating environment.
Ground the Instrument.
To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the
equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into an approved
three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an electrical ground
(safety ground) at the power outlet. The power jack and mating plug of the power cable meet International
Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes.
Do Not Operate in an Explosive Atmosphere.
Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical equipment in
such an environment constitutes a definite safety hazard.
Keep Away From Live Circuits.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other
qualified maintenance personnel may remove equipment covers for internal subassembly or component replacement
or any internal adjustment. Do not replace components with power cable connected. Under certain conditions,
dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power and
discharge circuits before touching them.
Use Caution When Exposing or Handling a CRT.
Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To prevent
CRT implosion, avoid rough handling or jarring of the equipment. Handling of a CRT should be done only by
qualified maintenance personnel using approved safety mask and gloves.
Do Not Substitute Parts or Modify Equipment.
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized
modification of the equipment. Contact your local Motorola representative for service and repair to ensure that safety
features are maintained.
Observe Dangerous Procedure Warnings.
Warnings, such as the example below, precede potentially dangerous procedures throughout this manual. Instructions
contained in the warnings must be followed. You should also employ all other safety precautions which you deem
necessary for the operation of the equipment in your operating environment.
!
WARNING
Dangerous voltages, capable of causing death, are present in
this equipment. Use extreme caution when handling, testing,
and adjusting.

Flammability
All Motorola PWBs (printed wiring boards) are manufactured with a flammability rating
of 94V-0 by UL-recognized manufacturers.

!
CAUTION
This equipment generates, uses and can radiate
electromagnetic energy. It may cause or be susceptible to
electromagnetic interference (EMI) if not installed and used
with adequate EMI protection.

This product contains a lithium battery to power the clock and calendar circuitry.
!
CAUTION
Danger ofexplosion ifbattery is replaced incorrectly. Replace
battery only with the same or equivalent type recommended
by the equipment manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
!
CAUTION
Il y a danger d’explosion s’il y a remplacement incorrect de la

type ou d’un type équivalent recommandé par leconstructeur.
Mettre au rebut les batteries usagées conformément aux
instructions du fabricant.
!
CAUTION
Explosionsgefahr bei unsachgemäßem Austausch der
Batterie. Ersatz nur durch denselben oder einen vom
Hersteller empfohlenen Typ. Entsorgung gebrauchter
Batterien nach Angaben des Herstellers.
