An invalid frame is either
– a frame which is not an integer number of 8 bits (n 8 bits) in length
– a frame which is too short taking into account the operation mode

selected via MODE3 (MDS3(2:0)) and the selection of receive CRC
ON/OFF (CCR4.RCRC3) as follows:
• MDS3(2:0)=011 (16 bit Address),
• MDS3(2:0)=010 (8 bit Address),
