arbitration phase

arbitration phase

The arbitration phase indicates those parts of the CAN FD data frame that utilize the bit timing as specified for Classical CAN. The arbitration phase starts with the SOF and lasts till the sample point of the BRS (bit rate switch) bit. In addition, the final part of the CAN FD data frame, starting with the sample point of the CRC delimiter till EOF completes the arbitration phase. The inter-frame space is also transmitted with the arbitration bit time. During the arbitration phase the nomi-nal bit time is used.
