Note: This bit is used to concatenate multiple message objects to
build a FIFO Buffer.
For single message objects (not belonging to a FIFO Buffer), this bit
must always be set to one.
0x0 = Data frame has 8 data bytes.
0x1 = Note: The data length code of a message object must be
defined the same as in all the corresponding objects with the same
identifier at other nodes. When the message handler stores a data
frame, it will write the DLC to the value given by the received
message.
