The Hub Feature Controller adds advanced functionality to the USB84604 by enabling the host to send commands
directly to it via the upstream USB connection. The Hub Feature Controller includes a USB peripheral/slave controller
that receives commands which are contained in the USB data packet. The following functions can be controlled via com-
mands through the Hub Feature Controller:
• I2C over USB Bridging: The host can send commands through USB to any device connected to the hub through
the SMBus.
• UART over USB Bridging: The host can send commands through USB to any device connected to the hub
through the UART. For more details about UART functions refer to the SDK.
• SPI over USB Bridging: The host accesses to an attached SPI device as a pass-through operation.
• GPIO Control: The GPIOs on the hub can be dynamically configured and controlled by the host. For more details
about GPIO functions refer to the SDK.
• OTP Programming: Permanent customer configurations can be loaded to the One Time Programmable memory.
• FlexConnect support: FlexConnect allows the hub to dynamically change the physical ports that act as upstream
and downstream ports. For more details refer to the FlexConnect Applications [ 9].
• Access to configuration registers
