 Arbitration field is displayed in frame
 Control field is displayed in frame
 Data field is displayed in frame

The list of decoding result:
 Time— the horizontal displacement between current frame and trigger
position.
 Type — the type of frames, “D” represents data frame, “R” represents
remote frame.
 ID — the id of frames, the oscilloscope can automatically detect the length
of frame’s id (11 bits or 27 bits).
 Length — the length of data field.
 Data — the value of data field.
 CRC — the value of CRC (Cyclic Redundancy Check) field.
