The control field sets “DLC” as the number of data bytes in the data field
(DLC = 0 to 8).

Note:
D: Dominant = 0
R: Recessive = 1
In a standard format frame, the control field’s IDE bit is the same as the r1 bit.
Caution:
In the remote frame, there is no data field even if the data length code is not 0000B.
