Motorola MVME2401-1 Installation And Use Manual page 4

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.
Throughout this manual, a convention is used which precedes data and address parameters
by a character identifying the numeric format as follows:
$
0x
%
&
For example, "12" is the decimal number twelve, and "$12" (hexadecimal) is the equivalent
of decimal number eighteen. Unless otherwise specified, all address references are in
hexadecimal.
An asterisk (*) following the signal name for signals which are level-significant denotes
that the signal is true or valid when the signal is low.
An asterisk (*) following the signal name for signals which 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:
Byte
Half word
Word
Double word
Document Terminology
Dollar
Specifies a hexadecimal character
Zero-x
Percent Specifies a binary number
Ampersand Specifies a decimal number
8 bits, numbered 0 through 7, with bit 0 being the least significant.
16 bits, numbered 0 through 15, with bit 0 being the least significant.
32 bits, numbered 0 through 31, with bit 0 being the least significant.
64 bits, numbered 0 through 63, with bit 0 being the least significant.
