     register is configured to have the number of data bits that will be clocked into the PRBS
     generator. This number of data bits is the number of clock periods that are given from the output
     clock. Once the number of data bits has been completed, the PRBS generator automatically stops
     running. The generator remains off until the enable pin goes low, which resets the generator, and
     then high again to start another "data bits" cycles of the PRBS.
