USB to UART Bridging with Microchip USB 2.0 Hubs
The USB to UART bridging feature of Microchip?s USB 2.0 hubs provides system designers with expanded system control and potential BOM reductions. When using this feature, a separate USB to UART device is no longer required and a downstream USB port is not lost, as occurs when a standalone USB to UART device is implemented. This feature is available on the Microchip USB2534, USB2533, USB2532, USB4604, and USB4624 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:
? Set UART Interface Baud Rate
? UART Write
? UART Read
