3. USB BLOCK DIAGRAM
The Serial Interface Engine (SIE) controls the USB data flow between the uCs and the USB bus. Port0
is a high speed (HS) transceiver for the upstream data path. The Hub Repeater is the traffic controller
which directs the bus data to and from the correct paths. The hub Controller and Function Controller
determines what data is to be written to or read from the various FIFOs. The Bus Controller directs the
interface between the uC and Hub/Function Controller.
