GCAN-212 user manual
0x12345678, and it contains 8 bytes of valid data (11h, 22h, 33h, 44h, 55h, 66h,
77h, 88h).

The following example is a UDP standard data frame, the frame ID is 0x123,
and it contains 8 bytes of valid data (11h, 22h, 33h, 44h, 55h, 66h, 77h, 88h)

Please note:
In the process of mutual conversion between CAN bus data and Ethernet data,
the CAN frame must be 13 bytes in the Ethernet data stream. If the CAN frame
ID is actually less than 4 bytes (standard frame or extended frame) or the CAN
frame data is actually less than 8 bytes, then the CAN frame will be converted
to Ethernet in less than 13 bytes, and the module will automatically fill in the
missing bits.
