8.20.8 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 8-45. 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)

8.20.9 Cable Diagnostic Amplitude Results Register 2 (CDARR2)

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 2 (CDARR2), address 0x0186

BIT NAME DEFAULT FUNCTION

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

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

Amplitude 4 (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 CDLRR2 (0x181)

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

6:0 TPTD Peak <000 0000>,RO Amplitude of the Third peak discovered by the TDR mechanism on Transmit Channel

Amplitude 3 (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 [7:0] in register CDLRR2 (0x181)

8.20.10 Cable Diagnostic Amplitude Results Register 3 (CDARR3)

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 8-47. Cable Diagnostic Amplitude Results Register 3 (CDARR3), address 0x0187

14:8 TPRD Peak <000 0000>,RO Amplitude of the First peak discovered by the TDR mechanism on Receive Channel (TPRD).

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 [15:8] in register CDLRR3 (0x182)

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