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 1000BASE-T is advertised then the required next pages are
automatically transmitted. Register 4.15 should be set to 0 if
no additional next pages are needed.
1 = Advertise
0 = Not advertised
Must be 0.
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.
1 = Set Remote Fault bit
0 = Do not set Remote Fault bit
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
Reserved bit is R/W to allow for forward compatibility with
future IEEE standards.
