21.2 CAN Protocol
automotive applications (class C). CAN is prescribed by ISO 11898. For details, refer to the ISO 11898 specifications.
link layer includes logical link and medium access control. The composition of these layers is illustrated below.
21.2.1 Frame format
1030
CAN (Controller Area Network) is a high-speed multiplex communication protocol for real-time communication in
The CAN specification is generally divided into two layers: a physical layer and a data link layer. In turn, the data
(1) Standard format frame
(2) Extended format frame
Note CAN controller specification
• The standard format frame uses 11-bit identifiers, which means that it can handle up to 2,048 messages.
• The extended format frame uses 29-bit (11 bits + 18 bits) identifiers, which increases the number of
• An extended format frame is set when “recessive level” (CMOS level of “1”) is set for both the SRR and IDE
