High-Performance, Low-Power System on Chip

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 EP7311 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.”

Pin Description Conventions

Abbreviations used for signal directions are listed in Table Z.
