8.7.5 Cable Diagnostic Location Results Register 3 (DDLRR3)

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).

Table 8-43. Cable Diagnostic Location Results Register 3 (DDLRR3), address 0x0182

BIT NAME DEFAULT FUNCTION

15:8 TPRD Peak 0000 0000, RO Location of the First peak discovered by the TDR mechanism on Receive Channel

Location 1 (TPRD). The value of these bits is translated into distance from the PHY.

7:0 TPTD Peak 0000 0000, RO Location of the Fifth peak discovered by the TDR mechanism on Transmit Channel

Location 5 (TPTD). The value of these bits is translated into distance from the PHY.

8.7.6 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).

Table 8-44. Cable Diagnostic Location Results Register 4 (CDLRR4), address 0x0183

BIT NAME DEFAULT FUNCTION

15:8 TPRD Peak 0000 0000, RO Location of the Third peak discovered by the TDR mechanism on Receive Channel

Location 3 (TPRD). The value of these bits is translated into distance from the PHY.

7:0 TPRD Peak 0000 0000, RO Location of the Second peak discovered by the TDR mechanism on Receive Channel

Location 2 (TPRD). The value of these bits is translated into distance from the PHY.

8.7.7 Cable Diagnostic Location Results Register 5 (CDLRR5)

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).

Table 8-45. Cable Diagnostic Location Results Register 5 (CDLRR5), address 0x0184

BIT NAME DEFAULT FUNCTION

15:8 TPRD Peak 0000 0000, RO Location of the Fifth peak discovered by the TDR mechanism on Receive Channel

Location 5 (TPRD). The value of these bits is translated into distance from the PHY.

7:0 TPRD Peak 0000 0000, RO Location of the Fourth peak discovered by the TDR mechanism on Receive Channel

Location 4 (TPRD). The value of these bits is translated into distance from the PHY.

8.7.8 Cable Diagnostic Amplitude Results Register 1 (CDARR1)

This register provides the peaks amplitude measurement after the execution of the TDR. The values of

this register are valid after reading 1 in Diagnostic Done bit 1 in register CDCR (0x1E).

Table 8-46. Cable Diagnostic Amplitude Results Register 1 (CDARR1), address 0x0185

BIT NAME DEFAULT FUNCTION

15 RESERVED 0,RO RESERVED: Writes ignored, read as 0.

14:8 TPTD Peak 000 0000, RO Amplitude of the Second peak discovered by the TDR mechanism on Transmit Channel

Amplitude 2 (TPTD). The value of these bits is translated into type of cable fault and-or interference.

This amplitude value refers to peak location stored in bits [15:8] in register CDLRR1 (0x180)

7 RESERVED 0, RO RESERVED: Writes ignored, read as 0.

6:0 TPTD Peak 000 0000, RO Amplitude of the First peak discovered by the TDR mechanism on Transmit Channel (TPTD).

Amplitude 1 The value of these bits is translated into type of cable fault and-or interference.

This amplitude value refers to peak location stored in bits [7:0] in register CDLRR1 (0x180)
