INTRODUCTION
The SMBus slave interface can be used to customize the functionality of the USB253x / USB3x13 / USB46x4 hub.
Through this interface, the SOC is able to control the digital and USB lines for internal testing, configure the Hub to func-
tion with the desired options when enumerating, and load custom firmware to fully unlock the features of the embedded
processor. This functionality entails that some configuration registers are accessible only during the configuration
stages, while others are accessible during runtime. Both sets of registers are detailed in this application note.
This document includes the following topics:
• HUB Operational Mode on page 2
•SOC Configuration Stage on page 3
•SMBus Run Time Accessible Registers on page 52
•OTP Configuration on page 61
