Reserved.
This bit selects the reference clock when the pattern (including PRBS, ARB & IB) is generated.
When the pattern is generated in the receive path:
0: XCLK. (default)
1: Recovered clock from the received signal.
When the pattern is generated in the transmit path:
0: XCLK. (default)
1: Transmit clock, i.e., the clock input on TCLKn (in Transmit Single Rail NRZ Format mode and in Transmit Dual Rail NRZ For-
mat mode) or the clock recovered from the data input on TDPn and TDNn (in Transmit Dual Rail RZ Format mode)
These bits select the pattern to be generated.
00: Disable. (default)
01: PRBS.
10: ARB.
11: IB.
This bit selects the pattern (including PRBS, ARB & IB) generation direction.
0: Transmit path. (default)
1: Receive path.
This bit controls whether to invert the generated PRBS/ARB pattern.
0: Normal. (default)
1: Invert.
