Description
=1, Auto negotiation is on
=0, Disable auto negotiation; speed and duplex are
determined by bits 6 and 5 of this register.
=1, Forced 100BT if AN is disabled (bit 7)
=0, Forced 10BT if AN is disabled (bit 7)
=1, Forced full duplex if (1) AN is disabled or (2) AN is
enabled but failed.
=0, Forced half duplex if (1) AN is disabled or (2) AN is
enabled but failed.
