Bit stuffing is used to establish synchronization by appending 1 bit of inverted-level data if the same level continues
As the bus priority (a node which acquires transmission rights) is determined by the identifier, any node can be the
Although there is one transmitting node, two or more nodes can receive the same data at the same time because
• During bus idle, the node that output data first transmits the data.
• The node that consecutively outputs the dominant level for the longest from the first bit of the arbitration field
• The transmitting node compares its output arbitration field and the data level on the bus.
• When a data frame and a remote frame are on the bus, the data frame has priority because its RTR bit, the
has the bus priority (if a dominant level and a recessive level are simultaneously transmitted, the dominant
level is taken as the bus value).
last bit in the arbitration field, carries a dominant level.
ID18 of both of them are the same), the standard-format remote frame takes priority.
During the transmission of a data frame or remote frame, when the same level continues for 5 bits in the data
between the start of frame and the ACK field, 1 inverted-level bit of data is inserted before the following bit.
During the reception of a data frame or remote frame, when the same level continues for 5 bits in the data
between the start of frame and the ACK field, reception is continued after deleting the next bit.
