The hard_temac v3_00_a and v3_00_b do not appear to have CRS and COL pins in the MII interface. Are these pins needed?
The MII_COL_# and MII_CRS_# ports in the COREGen wrapper files are connected to PHYEMAC#CRS and PHYEMAC#COL on the EMAC. These signals are only used in half duplex. Since the EDK hard_temac Core does not support half duplex, these signals are not brought out as ports.
