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)
=
TXP/TXM pins)
= 1, perform loopback, as indicated:
= 0, normal operation
0, force PHY into MDI-X mode (transmit on
Port 1 Loopback (reg. 29, bit 0 = ‘1’)
Port 2 Loopback (reg. 45, bit 0 = ‘1’)
Start: RXP2/RXM2 (port 2)
Loopback: PMD/PMA of port 1’s PHY
End: TXP2/TXM2 (port 2)
Start: RXP1/RXM1 (port 1)
Loopback: PMD/PMA of port 2’s PHY
End: TXP1/TXM1 (port 1)
