system interconnect applications with the device.
Document Conventions
This document uses the following conventions.
Non-differential Signal Notation
Non-differential signals are either active-low or active-high. An active-low signal has an active state of
logic 0 (or the lower voltage level), and is denoted by a lowercase “_b”. An active-high signal has an
active state of logic 1 (or the higher voltage level), and is not denoted by a special character. The
following table illustrates the non-differential signal naming convention.
State
Active low
Active high
Single-line signal
NAME_b
NAME
Multi-line signal
NAME_b[3]

Object Size Notation
•
•
•
A
byte
is an 8-bit object.
A
word
is a 16-bit object.
A
doubleword
(Dword) is a 32-bit object.
Numeric Notation

•
Binary numbers are denoted by the prefix
0b
(for example, 0b010).
Registers that have multiple iterations are denoted by {x..y} in their names; where
x
is first register
and address, and
y
is the last register and address. For example, REG{0..1} indicates there are two
versions of the register at different addresses: REG0 and REG1.
Symbols
p
Ti
This symbol indicates a basic design concept or information considered helpful.
This symbol indicates important configuration information or suggestions.
This symbol indicates procedures or operating levels that may result in misuse or damage to
the device.
