WebCRC: The Cyclic Redundancy Check (CRC) is 15 bit in the Classical CAN, while in CAN FD it's 17 bits (for up to 16 data bytes) or 21 bits (for 20-64 data bytes). In Classical CAN, there can be 0 to 3 stuff bits in the CRC, while in CAN FD there are always four fixed stuff bits to improve communication reliability.
