Description
LED Off
1 = turn off all of the port 2 LEDs (P2LED3,
P2LED2, P2LED1, P2LED0). These pins are
driven High if this bit is set to 1.
0 = normal operation.
Txids
1 = disable 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 (see Figure 15):
Start: RXP1/RXM1 (port 1).
Loopback: PMD/PMA of port 2’s PHY.
End: TXP1/TXM1 (port 1).
0 = normal operation.
Auto Negotiation Enable
0 = disable auto negotiation, speed and duplex are
decided by bits 6 and 5 of the same register.
1 = auto negotiation is ON.
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 the link partner.
