TX_GEN:
The Transmit Path Generate, TX_GEN, bit controls the output of the PRBS generator. When
TX_GEN is set to logic 1, the PRBS generator output is inserted into the transmit path. When
TX_GEN is set to logic 0, the transmit path functions normally.
RX_GEN:
The Receive Path Generate, RX_GEN, bit controls the output of the PRBS generator. When
RX_GEN is set to logic 1, the PRBS generator output is inserted into the receive path. When
RX_GEN is set to logic 0, the receive path functions normally.
TX_DET:
The Transmit Path Detect, TX_DET, bit controls the input of the PRBS checker. When
TX_DET is set to logic 1, the PRBS checker monitors the transmit path. When TX_DET is set
to logic 0, the PRBS detector monitors the receive path.
