Register Conventions
The following table lists the register conventions that are
specific to this manual. A more detailed set of register con-
ventions is located in the
Register Reference chapter on

Numeric Naming
Hexadecimal numbers are represented with all letters in
uppercase with an appended lowercase ‘h’ (for example,
‘14h’ or ‘3Ah’) and
hexadecimal
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
.
