Management of bulk/interrupt/isochronous endpoints
Buffer to store the data received on control endpoint (SETUP/OUT endpoint 0) Used to avoid a RAM buffer overflow in case of the payload buffer is smaller than control endpoint size The UDD manages the data transfer on endpoints: Start data transfer on endpoint with USB Device DMA Send a ZLP packet if requested Call callback registered to signal end of transfer The transfer abort and stall feature are supported.
