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 could result
in personal injury or damage to the equipment.
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 any explosive atmosphere such as in the presence of flammable gases or fumes.
Operation of any electrical equipment in such an environment could result in an explosion and cause injury or damage.
Keep Away From Live Circuits Inside the Equipment.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other
qualified service personnel may remove equipment covers for internal subassembly or component replacement or any
internal adjustment. Service personnel should not replace components with power cable connected. Under certain
conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, such personnel
should always disconnect power and discharge circuits before touching components.
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, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling of a CRT
should be done only by qualified service personnel using approved safety mask and gloves.
Do Not Substitute Parts or Modify Equipment.
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 all safety features are maintained.
Observe Warnings in Manual.
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
To prevent serious injury or death from dangerous voltages, use extreme
caution when handling, testing, and adjusting this equipment and its
components.

Flammability
All Motorola PWBs (printed wiring boards) are manufactured with a flammability rating
of 94V-0 by UL-recognized manufacturers.
EMI Caution
!
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.
Lithium Battery Caution
This product contains a lithium battery to power the clock and calendar circuitry.
!
Caution
Dangerof explosion ifbattery isreplaced incorrectly.Replace batteryonly
with the same or equivalent type recommended by the equipment
manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
Attention
!Il y a danger d’explosion s’il y a remplacement incorrect de la batterie.
Remplacer uniquement avec une batterie du même type ou d’un type
équivalent recommandé par le constructeur. Mettre au rebut les batteries
usagées conformément aux instructions du fabricant.
Vorsicht
!Explosionsgefahr bei unsachgemäßem Austausch der Batterie. Ersatz nur
durch denselben oder einen vom Hersteller empfohlenen Typ. Entsorgung
gebrauchter Batterien nach Angaben des Herstellers.

CE Notice (European Community)
Motorola Computer Group products with the CE marking comply with the EMC Directive
(89/336/EEC). Compliance with this directive implies conformity to the following
European Norms:
EN55022 “Limits and Methods of Measurement of Radio Interference Characteristics
of Information Technology Equipment”; this product tested to Equipment Class B
EN50082-1:1997 “Electromagnetic Compatibility—Generic Immunity Standard,
Part 1. Residential, Commercial and Light Industry”
System products also fulfill EN60950 (product safety) which is essentially the requirement
for the Low Voltage Directive (73/23/EEC).
Board products are tested in a representative system to show compliance with the above
mentioned requirements. A proper installation in a CE-marked system will maintain the
required EMC/safety performance.
In accordance with European Community directives, a “Declaration of Conformity” has
been made and is on file within the European Union. The “Declaration of Conformity” is
available on request. Please contact your sales representative.

Preface
The MVME5100 Single Board Computer Programmer’s Reference Guide provides the
information you will need to program your MVME5100 Single Board Computer.
The MVME5100 is a high-performance VME single board computer featuring the
Motorola Computer Group (MCG) PowerPlus II architecture with a choice of PowerPC®
processors—either Motorola’s MPC7400 with AltiVec™technology for algorithmic
intensive computations or the low-power MPC750.
As of the printing date of this manual, the MVME5100 is available in the configurations
shown below. All models of the MVME5100 are available with either VME SCANBE
front panel (-01x1) or IEEE 1101 compatible front panel (-01x3).

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 used for 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 theCtrl key and the
letter simultaneously, for example, Ctrl-d.

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:
0x Specifies a hexadecimal number
% Specifies a binary number
& Specifies a decimal number
Byte 8 bits, numbered 0 through 7, with bit 0 being the least significant.
Half word 16 bits, numbered 0 through 15, with bit 0 being the least significant.
Word 32 bits, numbered 0 through 31, with bit 0 being the least significant.
Double word 64 bits, numbered 0 through 63, with bit 0 being the least significant.
