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 and the copper link goes down.
If 1000BASE-T is advertised then the required next pages are
automatically transmitted. Register 4.15 should be set to 0b if no
additional next pages are needed.
1b = Advertise.
0b = Not advertised.
