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.
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.
Advertised flow control capability.
1 = advertise flow control (pause) capability.
0 = suppress flow control (pause) capability from
transmission to link partner.
Advertised 100BT full-duplex capability.
1 = advertise 100BT full-duplex capability.
0 = suppress 100BT full-duplex capability from
transmission to link partner.
