In our previous episode, Michael Schnell said: > More characteristics that can be differ in certain applications are > - bit count > - starting value > - shift count (only data block bits or data block bits plus CRC bits - Shift direction. msbit first, lsbit first, in case of wordwise crc also low/hi byte. - in case of (d)wordwise CRCs padding value. > - order of the bits (including bits in bytes and/or words), as well in > the data block as in the CRC itself > - sometimes the data bits are inverted before the CRC calculation, > sometimes the CRC bits are inverted before transmission.
