+ | * What is the purpose of delimiters in CAN frame? HZ: The recessive formated delimiter bits are needed for resynchronization purpose of the nodes in one network by means of a falling edge. They surround the ACK bit which is send in recessive state by the transmitter and is overwritten by a dominant state by all receiving nodes that have sucessfully checked the CRC. | ||
