Documentation Conventions
There are only four distinguishing font types used in this
manual, besides those found in the headings.
Register Conventions
This table lists the register conventions that are specific to
this manual. A more detailed set of register conventions is

Register Conventions
Numeric Naming
Hexidecimal numbers are represented with all letters in
uppercase with an appended lowercase ‘h’ (for example,
‘14h’ or ‘3Ah’) and hexidecimal numbers may also be rep-
resented by a ‘0x’ prefix, the C coding convention. Binary
numbers have an appended lowercase ‘b’ (for example,
01010100b’ or ‘01000011b’). Numbers not indicated by an
‘h’ or ‘b’ are decimal.
