1.3 General Conventions
Hexadecimal numbers are presented with all letters
in uppercase and a lowercase ‘h’ appended or with
a 0x at the beginning. For example, 0x14 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’, 0x 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 de-
termined’, ‘n/a’ designates ‘not available’, and
‘n/c’ indicates a pin that is a ‘no connect’.
