WebThe SYNC protocol provides the basic network synchronization mechanism. The SYNC producer triggers the synchronization object (SYNC) periodically. The transmission … WebISO CAN norm requires that each bit period is split to 8-25 time quanta, which means that CAN system clock is 8-25 times faster than the nominal bit rate. Each bit period begins with a SYNC_SEG, the duration of which is fixed to one TQ. Transmitting node begins to drive the bus at the beggining of the SYNC_SEG, whereas a correctly synchronized ...
