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
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
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.
Advertised flow control capability.
1 = advertise flow control (pause) capability.
0 = suppress flow control (pause) capability from
transmission to link partner.
