Frame format setting (IDE bit) and number of identifier (ID) bits
<3> Control field
The control field sets “N” as the number of data bytes in the data field
(N = 0 to 8).
Control field
D: Dominant = 0
R: Recessive = 1
In a standard format frame, the control field’s IDE bit is the same as the r1 bit.
Data length setting
In the remote frame, there is no data field even if the data length code is not
0000B.
