To ensure enough transitions to maintain synchronization, a bit of opposite polarity is inserted after five consecutive bits of the same polarity. This practice is called bit stuffing, and is necessary due to the non-return-to-zero (NRZ) coding used with CAN. The stuffed data frames are destuffed by the receiver. All fields in the frame are stuffed with the exception of the CRC delimiter, AC… WebApr 26, 2024 · CAN bus considers the 11 bit indentifiers to have a higher priority than the 29 bit identifiers (because the two types of "protocol", "11" and "29", can coexist in the same bus).
