If the software has budgeted the schedule of this data stream with a frame wrap case, then it must initialize
the siTD[Back Pointer] field to reference a valid siTD and have the T bit in the siTD[Back Pointer] field
cleared. Otherwise, the software must set the T bit in siTD[Back Pointer]. The host controller's rules for
interpreting when to use the siTD[Back Pointer] field are listed below. These rules apply only when the
