The LIN protocol defines a message frame format, shown in Figure 13-237. Each frame includes one commander header, one response, one in-frame response space, and inter-byte spaces. In-frame-response and inter-byte spaces can be 0.
There is no arbitration in the definition of the LIN protocol; therefore, multiple responder nodes responding to a header can be detected as an error.
The LIN bus is a single-channel wired-AND bus. The bus has a binary level: either dominant for a value of 0 or recessive for a value of 1.
