Conventions

Conventions that this specification can use are described in:

Typographical

This specification uses the following typographical conventions:

italic

Highlights important notes, introduces special terminology, denotes internal cross-references, and citations.

bold

Highlights interface elements, such as menu names. Denotes signal names. Also used for terms in descriptive lists, where appropriate.

monospace

Denotes text that you can enter at the keyboard, such as commands, file and program names, and source code.

monospace

Denotes a permitted abbreviation for a command or option. You can enter the underlined text instead of the full command or option name.

monospace italic

Denotes arguments to monospace text where the argument is to be replaced by a specific value.

monospace bold

Denotes language keywords when used outside example code.

< and >

Enclose replaceable terms for assembler syntax where they appear in code or code fragments. For example:

MRC p15, 0 <Rd>, <CRn>, <CRm>, <Opcode_2>

Numbering

A numbering convention used in this specification is:

<size in bits>'<base><number>

This is a Verilog® method of abbreviating constant numbers. For example:

  • 'h7B4 is an unsized hexadecimal value.

  • 8'd9 is an 8-bit wide decimal value of 9.

  • 8'h3F is an 8-bit wide hexadecimal value of 0x3F. This is equivalent to b0011 1111.

  • 8'b1111 is an 8-bit wide binary value of b0000 1111.
