A write to this register bit does not take effect until any one of
the following occurs:
Software reset is asserted (Register 0_0.15)
Restart Auto-Negotiation is asserted (Register 0_0.9)
Power down (Register 0_0.11, 16_0.2) transitions from power
down to normal operation
Copper link goes down.
If register 0_0.12 is set to 0 and speed is manually forced to
1000 Mbps in Registers 0_0.13 and 0_0.6, then Auto-
Negotiation will still be enabled and only 1000BASE-T full-
duplex is advertised if register 0_0.8 is set to 1, and
1000BASE-T half-duplex is advertised if 0_0.8 set to 0.
Registers 4_0.8:5 and 9_0.9:8 are ignored. Auto-Negotiation
is mandatory per IEEE for proper operation in 1000BASE-T.
Upon hardware reset this bit takes on the value of C_ANEG[1].
