Conventions
This section describes the conventions that this manual uses:
• Typographical
• Timing diagrams
• Signal naming on page xix
• Numbering on page xx.
Typographical
This manual 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 
ARM processor 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 >  Angle brackets enclose replaceable terms for assembler syntax 
where they appear in code or code fragments. They appear in 
normal font in running text. For example:
•
MRC p15, 0 <Rd>, <CRn>, <CRm>, <Opcode_2>
• The Opcode_2 value selects which register is accessed.
Timing diagrams
This manual contains one or more timing diagrams. The figure named Key to timing 
diagram conventions on page xix  on page xix explains the components used in these 
diagrams. When variations occur they have clear labels. You must not assume any 
timing information that is not explicit in the diagrams.
