M3 Universal Serial Bus (Usb) Controller - Texas Instruments Concerto F28M35 Series Technical Reference Manual

The USB controller operates as a full-speed or low-speed function controller during point-to-point
communications with USB Host, Device, or OTG functions. The controller complies with the USB 2.0
standard, which includes SUSPEND and RESUME signaling. Thirty-two endpoints comprised of two hard-
wired for control transfers (one endpoint for IN and one endpoint for OUT) plus 30 endpoints defined by
firmware along with a dynamic sizable FIFO, support multiple packet queueing. DMA access to the FIFO
allows minimal interference from system software. Software-controlled connect and disconnect allows
flexibility during USB device start-up. The controller complies with the OTG standard's session request
protocol (SRP) and host negotiation protocol (HNP).
