[bit9:0] count: Alignment errors
A 10-bit register counting the number of frames that are not an integral number of bytes long and have
bad CRC when their length is truncated to an integral number of bytes and are between 64 and 1518
bytes in length (1536 if bit 8 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 does not have an integral number of bytes.
