Description:
The USB to GPIO bridging feature of Microchip?s USB 2.0 hubs provides system designers expanded system control and potential BOM reduction. General Purpose Input/Outputs (GPIOs) may be used for any general 3.3V level digital control and input functions. This feature is available on Microchip hubs which contain the internal Hub Feature Controller. These hubs include the USB2532, USB2533, USB2534, USB3613, USB3813, USB4604, USB4624. Commands may be sent from the USB Host to the internal Hub Feature Controller device in the Microchip hub to perform the following functions: ? Set the direction of the GPIO (input or output) ? Enable a pull-up resistor ? Enable a pull-down resistor ? Read the state ? Set the state
