3.9 and Figure 3.10. CAN frames only indicate the following useful information: frame type, frame ID, data
length and data field. The "Frame Type" and "Frame ID" in the CAN frame are determined by the user's
configuration and remain unchanged all the time unless the user reconfigures the product. The "data length"
in the CAN frame is determined according to the actual number of bytes of data allocated to the CAN
frame.

(transparent conversion, data no more than 8 bytes)
