In Transmit Clock Master mode:
= 0: The source of the transmit clock is selected from the clock generated by the internal clock generator (2.048 MHz).
= 1: The source of the transmit clock is selected from the recovered clock from the line side.
In Transmit Clock Master mode, the Transmit Buffer is bypassed automatically.
In Transmit Clock Slave mode and in Transmit Multiplexed mode:
= 0: The source of the transmit clock is selected from the clock from the backplane. The Transmit Buffer is bypassed.
= 1: The source of the transmit clock is selected from the clock generated by the internal clock generator (2.048 MHz). The Transmit Buffer is not
= 0: The data is not inverted before extracted to the pattern detector.
= 1: The data is inverted before extracted to the pattern detector.
= 0: The generated pattern is not inverted.
= 1: The generated pattern is inverted.
These bits select the PRBS generated and detected pattern.
