Force_lnk
Force link.
1 = force link pass; 0 = normal operation.
Reserved.
Remote (Near-end) loopback (rlb)
1 = perform remote loopback at PHY
(RXP1/RXM1 -> TXP1/TXM1, see Figure 10)
0 = normal operation
Vct_fault_count
VCT fault count.
Distance to the fault. It’s approximately
0.4m*vct_fault_count.
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
1 = restart auto-negotiation.
0 = normal operation.
Reserved
Reserved
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.
Reserved
Auto Negotiation Enable
1 = auto negotiation is enabled.
0 = disable auto negotiation, speed, and duplex are
decided by bits 6 and 5 of the same register.
Force Speed
1 = force 100BT if AN is disabled (bit 7).
0 = force 10BT if AN is disabled (bit 7).
Force Duplex
1 = force full duplex if (1) AN is disabled or (2) AN
is enabled but failed.
0 = force half duplex if (1) AN is disabled or (2) AN
is enabled but failed.
