26.3.1.3.4. Data Length Code (DLC[3:0])

DLC specifies the number of data bytes in the data frame. The maximum number is eight.

The data length code (DLC) of a message object must be defined the same as in all the corresponding objects with the same identifier in all CAN devices. When the message handler stores a data frame, it sets the DLC field to the value provided in the received message.
