The START OF FRAME (SOF) marks the beginning of DATA FRAMES and REMOTE
FRAMES. It consists of a single ‘dominant’ bit. A station is only allowed to start transmission
when the bus is idle. All stations have to synchronize to leading edge caused by START OF
FRAME of the station starting transmission first.
The format of ARBITRATION FIELD is different between Standard Format and Extended
Format Frames.
In Standard Format, the ARBITRATION FIELD consists of 11 bit IDENTIFIER and the RTR-
bit. The IDENTIFIER bits are denoted ID-28… ID-18.
In Extended Format, the ARBITRATION FIELD consists of the 29 bit IDENTIFIER, the SRR-
bit, the IDE-bit, and the RTR-bit. The IDENTIFIER bits are denoted ID-28… ID-0.
Note: In order to distinguish between Standard Format and Extended Format the reserved bit r1 is
denoted as IDE bit.
