RxERR in MII

Hi all,

i have a problem with my Ethernet PHY (DP83848C). The Ethernet PHY is connected with a medium independent inteface (MII) and the interface works well. But my frames have an error (the RxERR and the RxDV signals from MII are high).

The only reason one i know is a CRC-fault, there are other faults for RxERR?

Regards
