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

Counts frames that are an integral number of bytes, have bad CRC and are between 64 and 1518 bytes in length (1536 if bit 8 is set in Network Configuration register, 10240 bytes if bit 3 is set in the Network Configuration register). 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 being enabled in bit 26 of the Network Configuration register.
