+      USB RX packet threshold count. In host mode, this field specifies

+      In device mode, this field specifies the space that must be

+      flow-controlled endpoint. It is only used for SuperSpeed.
+      The valid values for this field are from 1 to 15. (DWC3 SuperSpeed

+      bus is slower than the USB, RX FIFO can overrun during a long burst.
+      You can program a smaller value to this field to limit the RX burst
+      size that the core can perform. It only applies to SS Bulk,
+      Isochronous, and Interrupt IN endpoints in the host mode.
+      In device mode, this field specifies the NUMP value that is sent in
+      ERDY for an OUT endpoint.
