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’.
