Description
Auto Negotiation Enable (Note 1)
1 = auto negotiation is enabled.
0 = disable auto negotiation, speed, and duplex are decided by bits 6
and 5 of the same register.
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.
