8.8.3 Cable Diagnostic Location Results Register 1 (CDLRR1)
This register provides the peaks locations after execution of the TDR. The values of this register are valid
after reading 1 in Diagnostic Done bit 1 in register CDCR (0x1E).

(TPTD). The value of these bits is translated into distance from the PHY
8.8.4 Cable Diagnostic Location Results Register 2 (CDLRR2)
This register provides the peaks locations after execution of the TDR. The values of this register are valid
after reading 1 in Diagnostic Done bit 1 in register CDCR (0x1E).

Location of the First peak discovered by the TDR mechanism on Receive Channel
(TPRD). The value of these bits is translated into distance from the PHY.
Location of the Fifth peak discovered by the TDR mechanism on Transmit Channel
(TPTD). The value of these bits is translated into distance from the PHY.
8.8.6 Cable Diagnostic Location Results Register 4 (CDLRR4)
This register provides the peaks locations after execution of the TDR. The values of this register are valid
after reading 1 in Diagnostic Done bit 1 in register CDCR (0x1E).
