LogiCORE 10 Gigabit Ethernet MAC and XAUI v4.0 cores - Data sheets incorrectly state that SIGNAL_DETECT is ignored when the XAUI interface is used as an XGXS block


General Description: 

The 10 Gigabit Ethernet MAC v4.0 and XAUI v4.0 data sheets incorrectly state that the SIGNAL_DETECT lines are ignored when the XAUI interface is used as an XGXS block.


This is true only when the XAUI block has an MDIO interface. When the version with the configuration vector is used, the XAUI block assumes it is a PCS and will use the SIGNAL_DETECT lines to drive/reset the internal sync state machine.
