Safety Summary

Safety Depends On You

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 speciÞc 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. The equipment is supplied with a three-conductor ac power cable. The power cable must be plugged into an approved three-contact electrical outlet. The power jack and mating plug of the power cable meet International Electrotechnical Commission (IEC) safety standards.

Do Not Operate in an Explosive Atmosphere.

Do not operate the equipment in the presence of ßammable gases or fumes. Operation of any electrical equipment in such an environment constitutes a deÞnite safety hazard.

Keep Away From Live Circuits.

Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other qualiÞed 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.

Do Not Service or Adjust Alone.

Do not attempt internal service or adjustment unless another person capable of rendering Þrst aid and resuscitation is present.

Use Caution When Exposing or Handling the CRT.

Breakage of the 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 the CRT should be done only by qualiÞed 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 modiÞcation of the equipment. Contact your local Motorola representative for service and repair to ensure that safety features are maintained.

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.

Dangerous voltages, capable of causing death, are

WARNING

present in this equipment. Use extreme caution when handling, testing, and adjusting.

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

This equipment generates, uses, and can radiate electro-

WARNING

magnetic energy. It may cause or be susceptible to electro-magnetic interference (EMI) if not installed and used in a cabinet with adequate EMI protection.

European Notice: Board 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 (CISPR 22) Radio Frequency Interference

EN50082-1 (IEC801-2, IEC801-3, IEEC801-4) Electromagnetic Immunity

The product also fulÞlls EN60950 (product safety) which is essentially the requirement for the Low Voltage Directive (73/23/EEC).

This board product was 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.

Terminology, Conventions, and Deﬁnitions Used in this Manual

Data and Address Parameter Numeric Formats

Throughout this manual, a character identifying the numeric format precedes data and address parameters as follows:

$ dollar speciÞes a hexadecimal character % percent speciÞes a binary number & ampersand speciÞes a decimal number

For example, Ò12Ó is the decimal number twelve, and Ò$12Ó is the decimal number eighteen.

Unless otherwise specified, all address references are in hexadecimal.

Signal Name Conventions

An asterisk (*) follows signal names for signals which are level or edge significant:

Term * Indicates

level

signiÞcant

edge

signiÞcant

1-2

The signal is true or valid when the signal is low.

The actions initiated by that signal occur on high to low transition.

Terminology, Conventions, and Definitions Used in this Manual

Assertion and Negation Conventions

Assertion and negation are used to specify forcing a signal to a particular state. These terms are used independently of the voltage level (high or low) that they represent.

Term Indicates

Assertion and assert

Negation and negate

The signal is active or true.

The signal is inactive or false.

Data and Address Size Deﬁnitions

Data and address sizes are defined as follows:

Name Size Numbered SigniÞcance Called

Byte 8 bits 0 through 7

Two-byte 16 bits 0 through 15

Four-byte 32 bits 0 through 31

Big-Endian Byte Ordering

bit 0 is the least signiÞcant

halfword

word

This manual assumes that the MPU on the MVME187 always programs the CMMUs with big-endian byte ordering, as shown below. Any attempt to use little-endian byte ordering will immediately render the MVME187Bug debugger unusable.

Board Level Hardware Description

Onboard Memory Mezzanine Module

The MVME187 onboard DRAM mezzanine boards are available in different sizes and with programmable parity protection or Error Checking and Correction (ECC) protection.

❏ The main board and a single mezzanine board together take

one slot.

❏ Motorola software supports mixed parity and ECC memory

boards on the same main board.

❏ Mezzanine board sizes are 4, 8, 16, or 32 MB (parity), or 4, 8,

16, 32, 64, or 128 MB (ECC); Ð Two mezzanine boards may be stacked to provide 256MB

of onboard RAM (ECC) or 64 MB (parity). The stacked configuration requires two VMEbus slots.

❏ The DRAM is four-way interleaved to efficiently support

cache burst cycles.

❏ The parity mezzanines are only supported on 25 MHz main

boards.

A functional description of the Onboard DRAM starts on page 2-15.

SCSI Mass Storage Interface

The MVME187 provides for mass storage subsystems through the industry-standard SCSI bus. These subsystems may include
