Introduction

1.7Notational-Conventions

The following notation conventions are consistent with other i960 RM/RN I/O processor documentation and general industry standards.

# or overbar

In code examples the pound symbol (#) is appended to a signal name to

 

indicate that the signal is active. Normally inverted clock signals are

 

indicated with an overbar above the signal name (e.g., RAS).

Bold

Indicates user entry and/or commands.

 

PLD signal names are in bold lowercase letters (e.g., h_off, h_on).

Italics

Indicates a reference to related documents; also used to show emphasis.

Courier font

Indicates code examples and file directories and names.

Asterisks (*)

On non-Intel company and product names, a trailing asterisk indicates

 

the item is a trademark or registered trademark. Such brands and names

 

are the property of their respective owners.

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

In text, instead of using subscripted “base” designators (e.g., FF 16) or

hexadecimal and

leading “0x” (e.g., 0xFF) hexadecimal numbers are represented by a

binary numbers

string of hex digits followed by the letter H. A zero prefix is added to

 

numbers that begin with A through F. (e.g., FF is shown as 0FFH.) In

 

examples of actual code, “0x” is used. Decimal and binary numbers are

 

represented by their customary notations. (e.g., 255 is a decimal number

 

and 1111 1111 is a binary number. In some cases, the letter B is added to

 

binary numbers for clarity.)
