WebThe bit rate is switched back from the XL data phase bit rate to the Nominal bit rate at the boundary between the FCP0 bit and the DAH bit in the DAS field. When the CAN transceiver mode switching is enabled, the time duration of the ADH bit and the DAH bit is used to signal the CAN transceiver to switch its operating modes. Webboundary for the bit rate as well as for the bus length. Therefore, new concepts to increase the CAN bit rate avoid this limit mainly by two alternatives. Firstly, the authors in [3][3][3] [5][5][5] [10][10][10] change CAN’s multi-master bus line to a star (or tree) topology where arbitration (or even message rout- iocl offers
