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, with bits listed in
brackets separated by a colon (:) (for example, CODR[7:0]),
and are described in the EP7309 User’s Manual. 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.”
