= 11: Reserved.
= 0: The pattern in the PRBS Generator/Detector is generated in the transmit path and is detected in the receive path.
= 1: The pattern in the PRBS Generator/Detector is generated in the receive path and is detected in the transmit path.
A transition from ‘0’ to ‘1’ on this bit initiates the PRBS Generator/Detector.
