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 the Microchip USB5734 and USB58xx/USB59xx USB3.1 Gen 1 Hubs. 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/Disable SPI Pass-Through Interface ?SPI Write ?SPI Read
