Bits 9:0 – FCKR[9:0] Frame Check Sequence Errors

The register counts frames that are an integral number of bytes, have bad CRC and are between 64 and 1518 bytes in length (1536 Bytes if NCFGR.MAXFS is written to '1'). This register is also incremented if a symbol error is detected and the frame is of valid length and has an integral number of bytes.

This register is incremented for a frame with bad FCS, regardless of whether it is copied to memory due to ignore FCS mode (enabled by writing NCFGR.IRXFCS=1).
