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, ‘11’ 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[0–2]).
The use of ‘tbd’ indicates values that are ‘to be determined’, ‘n/a’ designates ‘not available’, and
‘n/c’ indicates a pin that is a ‘no connect’.
