Cross TDR Diagnostic Mode:
0x0 = TDR looks for reflections on channel other than the transmit channel configured by 0x170
0x1 = TDR looks for reflections on same channel as transmit channel configured by 0x170
TDR TX channel select:
0x0 = Select channel A as transmit channel.
0x1 = Select channel B as transmit channel.
To make sure DC removal module is not reset before TDR and dc removal is effective on TDR reflection
Number of TDR Cycles to Average:
0x0 = 1 TDR cycle
0x1 = 2 TDR cycles
0x2 = 4 TDR cycles
0x3 = 8 TDR cycles
0x4 = 16 TDR cycles
0x5 = 32 TDR cycles
0x6 = 64 TDR cycles
0x7 = Reserved
Selects cable segment on which TDR is to be performed - 000b = Reserved 001b = 0m to 10m 010b = 10m to 20m 011b = 20m to 40m 100b = 40m to 80m 101b = 80m and beyond 110b = Reserved 111b = Reserved
