Table 8-40. Cable Diagnostic Location Results Register 1 (CDLRR1), address 0x0180 (continued)
BIT NAME
7:0 TPTD Peak
Location 1
DEFAULT
<0000 0000>, RO
FUNCTION
Location of the First peak discovered by the TDR mechanism on Transmit Channel
(TPTD). The value of these bits is translated into distance from the PHY
8.20.4 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).
Table 8-41. Cable Diagnostic Location Results Register 2 (CDLRR2), address 0x0181
BIT NAME
15:8 TPTD Peak
Location 4
7:0 TPTD Peak
Location 3
DEFAULT
<0000 0000>, RO
<0000 0000>, RO
FUNCTION
Location of the Fourth peak discovered by the TDR mechanism on Transmit Channel
(TPTD). The value of these bits is translated into distance from the PHY.
Location of the Third peak discovered by the TDR mechanism on Transmit Channel
(TPTD). The value of these bits is translated into distance from the PHY.
8.20.5 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 8-42. Cable Diagnostic Location Results Register 3 (DDLRR3), address 0x0182
BIT NAME
15:8 TPRD Peak
Location 1
7:0 TPTD Peak
Location 5
DEFAULT
<0000 0000>, RO
<0000 0000>, RO
FUNCTION
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.
8.20.6 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 8-43. Cable Diagnostic Location Results Register 4 (CDLRR4), address 0x0183
BIT NAME
15:8 TPRD Peak
Location 3
7:0 TPRD Peak
Location 2
DEFAULT
<0000 0000>, RO
<0000 0000>, RO
FUNCTION
Location of the Third 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 Second peak discovered by the TDR mechanism on Receive Channel
(TPRD). The value of these bits is translated into distance from the PHY.
8.20.7 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 8-44. Cable Diagnostic Location Results Register 5 (CDLRR5), address 0x0184
BIT NAME
15:8 TPRD Peak
Location 5
7:0 TPRD Peak
Location 4
DEFAULT
<0000 0000>, RO
<0000 0000>, RO
FUNCTION
Location of the Fifth 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 Fourth peak discovered by the TDR mechanism on Receive Channel
(TPRD). The value of these bits is translated into distance from the PHY.
