By default, IXF1110 auto-negotiation is disabled by Register bit 5 (AN_enable) of the
Config ($ Port_Index +
forced mode, which is 1000 Mbps full duplex only. This is equivalent to entering the state
AN_DISABLE_LINK_OK as described in Figure 37-6 of IEEE 802.3. The IXF1110 can pass
packets when auto-negotiation is disabled only when the internal Synchronization State Machine
indicates that the sync_status is OK as described in Figure 36-9 of IEEE 802.3.
Packet IPG must contain a minimum of three consecutive /I1/ or /I2/ ordered sets per IEEE 802.3
for correct operation.
The IXF1110 treats the K28.1 code word as an unknown control word; therefore, it should not be
used.
Auto-Negotiation
Auto-negotiation is carried out by an internal state machine within the MAC in the IXF1110. The
IXF1110 is fully IEEE 802.3z standard compliant.
The following three registers are involved in this auto-negotiation process: RX Config Word
TX Config Word, and Diverse Config:

to determine when auto-negotiation is complete. The following MAC registers must be
programmed to match the results upon completion:
In auto-negotiation mode, the TX SPI4-2 status bus (TSTAT[1:0]) is held in the SATISFIED state
until auto-negotiation completes and a valid link is established. This prevents the TX FIFO from
being filled prior to transmission of packets.
Determining If Link Is Established in Auto-Negotiation Mode
A valid link is established when the (AN_complete) bit is set and the RX_Sync bit reports
synchronization has occurred. Both register bits are located in the
