General Conventions

Hexadecimal numbers are presented with all letters in uppercase and a lowercase h appended. For exam-

ple, 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 Table 5-1 and Table 5-2, 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’.
