The above figure is the packet format of CAN 2.0B. Users can map it to the example below
to understand the meaning of each column. To control the 62000B on Address, the ID
column can be got by the following conversion formula, see also CAN_Tx() Function in
section 4.4.5 Example Program:
ID = (PC_Address + (62000B_Address * (2 ^ 8))) * (2 ^ 13)
0x3FC000= (254 + (1 * (2 ^ 8))) * (2 ^ 13)
