INTEL 186 EB/EC EVALUATION BOARD USER’S MANUAL

1.2NOTATION CONVENTIONS

The following notation conventions are used in this manual.

#

Pound symbol (#) appended to a signal name indicates that the signal is

 

active low.

 

italics

Italics identify variables and indicate new terms.

bold sans-serif

In text, identifies commands (instructions).

typewriter

This font is used for code examples. All characters are equal width; this is

font

useful for maintaining accurate character spacing.

UPPERCASE

In text, signal names are shown in uppercase. When several signals share a

 

common name, each signal is represented by the signal name followed by a

 

number; the group is represented by the signal name followed by a variable

 

(n). In code examples, signal names are shown in the case required by the

 

software development tool in use.

Designations for

Hexadecimal numbers are represented by a string of hex digits followed by

hexadecimal and

the letter H. A zero prefix is added to numbers that begin with A through F.
