38.4 CAN Message Frames

The ISO11898-1 describes the different CAN message frames in detail. Figure 38-6 through Figure 38-10 explain and summarize the construction of the messages and fields.

There are two different CAN data/remote frames (see Figure 38-7):

CAN Base Frame: Classic CAN 2.0 frame using Standard ID
CAN Extended Frame: Classic CAN 2.0 frame using Extended ID

Figure 38-8 specifies the control field of the different CAN messages.

Figure 38-10 illustrates the error and overload frames. These special frames do not change.
