This bitwise arbitration technique is based on the use of dominant and recessive states on the bus, with the dominant states taking precedence over the recessive bits. In the event of a collision in the arbitration field (simultaneous sending of recessive and dominant bits), only those modules sending a dominant bit will keep on transmitting, while the others will cease to transmit. This process is repeated for each bit of the arbitration f
