1 = advertise flow control capability.
0 = suppress flow control capability from transmission
to link partner.
1 = advertise 100BT full-duplex capability.
0 = suppress 100BT full-duplex capability from
transmission to link partner.
1 = advertise 100BT half-duplex capability.
0 = suppress 100BT half-duplex capability from
transmission to link partner.
1 = advertise 10BT full-duplex capability.
0 = suppress 10BT full-duplex capability from
transmission to link partner.
1 = advertise 10BT half-duplex capability.
0 = suppress 10BT half-duplex capability from
transmission to link partner.
Description
1 = turn off all port’s LEDs (LEDx_2, LEDx_1, LEDx_0,
where “x” is the port number). These pins will be driven
high if this bit is set to one.
0 = normal operation.
1 = disable port’s transmitter.
0 = normal operation.
1 = restart auto-negotiation.
0 = normal operation.
1 = disable far end fault detection and pattern transmission.
0 = enable far end fault detection and pattern transmission.
1 = power down.
0 = normal operation.
1 = disable auto MDI/MDIX function.
0 = enable auto MDI/MDIX function.
1 = if auto MDI/MDIX is disabled, force PHY into
MDI mode.
0 = do not force PHY into MDI mode.
1 = perform “local loopback”, ie., loopback PHYs TX
back to RX.
0 = normal operation.
Description
1 = forced full-duplex if (1) AN is disabled or (2) AN is
enabled but failed.
0 = forced half-duplex if (1) AN is disabled or (2) AN is
enabled but failed.
