• Signals on page xxiii.
Typographical
The typographical conventions are:
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 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>
