Description
1 = Turn off all port’s LEDs (LEDx_3, 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 the 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/MDI-X function
0 = Enable auto MDI/MDI-X function
If auto MDI/MDI-X is disabled,
1 = Force PHY into MDI mode (transmit on RXP/RXM pins)
0 = Force PHY into MDI-X mode (transmit on TXP/TXM pins)
1 = Perform loopback, as indicated:
0 = Normal operation
Description
1 = MDI-X
0 = MDI
1 = Auto-negotiation completed
0 = Auto-negotiation not completed
1 = Link good
0 = Link not good
Port 1 Loopback (reg. 29, bit 0 = ‘1’)
Start: RXP2/RXM2 (port 2)
Loopback: PMD/PMA of port 1’s PHY
End: TXP2/TXM2 (port 2)
Port 2 Loopback (reg. 45, bit 0 = ‘1’)
Start: RXP1/RXM1 (port 1)
Loopback: PMD/PMA of port 2’s PHY
End: TXP1/TXM1 (port 1)
