Force_lnk
Force link.
1 = force link pass.
0 = normal operation.
pwrsave
Power-saving.
1 = disable power saving.
0 = enable power saving.
Remote (Near-End) Loopback (rlb)
1 = perform remote loopback at Port 1's PHY (RXP1/RXM1 ->
TXP1/TXM1, see Figure 15)
0 = normal operation
Reserved
Description
LED Off
1 = Turn off all of the port 1 LEDs (P1LED3, P1LED2, P1LED1,
P1LED0). These pins are driven high if this bit is set to one.
0 = normal operation.
Txids
1 = disable the port’s transmitter.
0 = normal operation.
Restart AN (Note 1)
1 = restart auto-negotiation.
0 = normal operation.
Disable Far-End-Fault
1 = disable far-end-fault detection and pattern transmission.
0 = enable far end fault detection and pattern transmission.
Power Down
1 = power down.
0 = normal operation.
Disable auto MDI/MDI-X
1 = disable auto MDI/MDI-X function.
0 = enable auto MDI/MDI-X function.
Force MDI-X
1= if auto MDI/MDI-X is disabled, force PHY into MDI-X mode.
0 = do not force PHY into MDI-X mode.
Far-End Loopback
1 = perform loopback, as indicated:
Start: RXP2/RXM2 (port 2).
Loopback: PMD/PMA of port 1’s PHY.
End: TXP2/TXM2 (port 2).
0 = normal operation.
Auto Negotiation Enable (Note 1)
