This document contains conventions for numeric values as follows.

Hexadecimal Notation

This section defines the typographical convention used throughout this book. All hex numbers are followed by an “h.” Examples:

All binary numbers are followed by a “b.” Examples:

16
255
256d
128d

Bits Versus Bytes Notation

All abbreviations for “bits” use lower case. For example:

• 2.5Gb/s = 2.5 Gigabits per second.

• 2Mb = 2 Megabits.

All references to “bytes” are specified in upper case. For example:

• 10MB/s = 10 Megabytes per second.

• 2KB = 2 Kilobytes.

Other designations:

• “lsb” refers to the least-significant bit.

• “LSB” refers to the least-signicant byte.

• “msb” refers to the most-significant bit.

• “MSB” refers to the most-significant byte.

Bit Fields (Logical Groups of Bits or Signals)

In many cases, bit fields are documented as [15:8], with this example referring to bits 8 through 15.
