Notes:
1. This part supports the 1000 Base-T with SerDes interface by default. It can operate in 10/100/1000
Base-T with SGMII interface by reconfiguration of the PHY within the SFP.
2. This part uses the SFP's Rx-Los pin for link indication and 1000 Base-T auto-negotiation should be
disabling on the host system. It can operate in 10/100/1000 Base-T with SGMII interface by
reconfiguration of the PHY within the SFP.
3. This part supports the 10/100/1000 Base-T with SGMII interface by default. It can operate in 1000
Base-T with SerDes interface by reconfiguration of the PHY within the SFP.

Description
Changes to these bits are disruptive to the normal
operation; hence, any changes to these registers must be
followed by software reset to take effect.
Upon hardware reset Register 27.3:0 defaults to the value
in HWCFG_MODE[3:0].
0100 = SGMII without Clock with SGMII Auto-Neg to
copper
1000 = 1000BASE-X without Clock with 1000BASE-X
Auto-Neg to copper (GBIC)
