WebThe CAN protocol has defined a recessive (logic ‘1’) and dominant (logic ‘0’) state to implement a non-destructive bit-wise arbitration scheme. It is this arbitra-tion methodology that is affected most by propagation delays. Each node involved with arbitration must be able to sample each bit level within the same bit time. Web1.5.4 BIT TIMING LOGIC The Bit Timing Logic (BTL) monitors the bus line input and handles the bus related bit timing according to the CAN protocol. The BTL synchronizes on a recessive-to-dominant bus transition at the Start-of-Frame (hard synchronization) and on any further recessive-to-dominant bus line transition if the CAN controller itself
