258 USB RX packet threshold count. In host mode, this field specifies
259 the space that must be available in the RX FIFO before the core can
260 start the corresponding USB RX transaction (burst).
262 available in the RX FIFO before the core can send ERDY for a
263 flow-controlled endpoint. It is only used for SuperSpeed.

272 Max USB RX burst size. In host mode, this field specifies the
274 bus is slower than the USB, RX FIFO can overrun during a long burst.
275 You can program a smaller value to this field to limit the RX burst
276 size that the core can perform. It only applies to SS Bulk,
