1.3 General Conventions
Hexadecimal numbers are presented with all letters in uppercase and a lowercase h appended. For
example, 14h and 03CAh are hexadecimal numbers. Binary numbers are enclosed in single quotation
marks when in text (for example, â11â designates a binary number). Numbers not indicated by an h
or quotation marks are decimal.
Registers are referred to by acronym, as listed in the tables on the previous page, with bits listed in
brackets MSB-to-LSB separated by a colon (:) (for example, CODR[7:0]), or LSB-to-MSB
separated by a hyphen (for example, CODR[0â2]).
The use of âtbdâ indicates values that are âto be determinedâ, ân/aâ designates ânot availableâ, and
ân/câ indicates a pin that is a âno connectâ.
1.4 Pin Description Conventions
