Bits 9:0 – UFRX[9:0] Undersize Frames Received
This bit field counts the number of frames received less than 64 bytes in length (10/100 mode, full duplex) that do not have either a CRC error or an alignment error. In gigabit half duplex mode this register counts either frames not conforming to the minimum slot time of 512 bytes or frames not conforming to the minimum frame size once bursting is active.
