Description
Power down
1 = power down
0 = normal operation
Disable auto MDI/MDIX
1 = disable auto MDI/MDIX function
0 = enable auto MDI/MDIX function
Force MDIX
1 = If auto MDI/MDIX is disabled, force PHY into
MDIX mode
0 = Do not force PHY into MDIX mode
Loop back
1 = perform loop back, as indicated:
Start: RXP1/RXM1 (port 1)
Loop back: 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 bit 6 and 5 of the same register.
1 = auto negotiation is ON
Force Speed
1 = force 100Base-T if AN is disabled (bit 7)
0 = force 10Base-T 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 100Base-T Full duplex capability
0 = suppress 100Base-T Full duplex capability from
transmission to link partner
Advertised 100BT half duplex capability
1 = advertise 100Base-T Half duplex capability
0 = suppress 100Base-T Half duplex capability from
transmission to link partner
Advertised 10BT Full duplex capability
1 = advertise 10Base-T Full duplex capability
0 = suppress 10Base-T Full duplex capability from
transmission to link partner
Advertised 10BT half duplex capability
1 = advertise 10Base-T Half duplex capability
0 = suppress 10Base-T Half duplex capability from
transmission to link partner
