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: 

For example, “12” is the decimal number twelve, and “$12” 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:

$ dollar specifies a hexadecimal character

% percent specifies a binary number

& ampersand specifies a decimal number

Term * Indicates

level 

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

edge 

significant

The actions initiated by that signal occur on high 

to low transition. 

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.

Data and Address Size Definitions

Data and address sizes are defined as follows: 

Big-Endian Byte Ordering

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. 

Term Indicates

Assertion and assert The signal is active or true.

Negation and negate The signal is inactive or false.

Two-byte 16 bits 0 through 15

bit 0 is the

Control and Status Bit Definitions

The terms control bit and status bit are used extensively in this 

document to describe certain bits in registers. 

❏ The status bit can be read by software to determine 

operational or exception conditions. 

True/False Bit State Definitions

True and False indicate whether a bit enables or disables the 

function it controls:

Bit Value Descriptions

In all tables, the terms 0 and 1 are used to describe the actual value 

that should be written to the bit, or the value that it yields when 

read. 

Term Describes

Control bit The bit can be set and cleared under software 

control.

Status bit The bit reflects a specific condition.

Term Indicates 

True Enables the function it controls.

False Disables the function it controls.

Related Documentation

The MVME187 ships with a start-up installation guide 

(MVME187IG/D, the document you are presently reading) which 

includes installation instructions, jumper configuration 

information, memory maps, debugger/monitor commands, and 

any other information needed for start-up of the board.

If you wish to develop your own applications or need more detailed 

information about your MVME187 Single Board Computer, you 

may purchase the additional documentation (listed on the 

following pages) through your local Motorola sales office.

If any supplements have been issued for a manual or guide, they 

will be furnished along with the particular document. Each 

Motorola Computer Group manual publication number is suffixed 

with characters which represent the revision level of the document, 

such as “/D2” (the second revision of a manual); a supplement 

bears the same number as a manual but has a suffix such as 

“/D2A1” (the first supplement to the second edition of the 

manual).
