WebCAN bus bit stuffing. Notice that we highlighted 'bit stuffing' across the CAN frame. Bit stuffing is a subtle, but vital part of the CAN standard. Basically it states that whenever a CAN node sends five bits of the same logic level (dominant or recessive), it must send one bit of the opposite level.
