WebCAN Protocol Engine The CAN protocol engine consists primarily of the Bit Timing Logic (BTL) and the Bit Stream Processor (BSP) modules. Figure 2 illustrates a block diagram of the CAN protocol engine. Bit Timing Logic The primary functions of the Bit Timing Logic (BTL) module include: † Synchronizing the CAN controller to CAN traffic on the bus Web3 Bit timing configuration. Configuring the bit timing registers, it is possible to define the position of the sample point for all the bits that the controller gets on the bus and the baud-rate as well.
