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.”
