Description
The USB to SPI bridging feature of Microchip hubs provides system designers with expanded system control and potential BOM reductions. When using Microchip's USB hubs, a separate USB to SPI device is no longer required and a downstream USB port is not lost, as occurs when a standalone USB to SPI device is implemented. This feature is available on Microchip hubs which contain the internal Hub Feature Controller and a SPI Interface. These hubs include USB3613, USB3813, USB4604, and 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: - Enable SPI Pass-Through Interface - SPI Write/Read - Disable SPI Pass-Through Interface
