The addresses in the following table denote the address offsets to the CAN #n message buffer base
address: CnMBaseAddr, with m being the message buffer number.
Example
CAN0, message buffer m = 14 = E
C0MBaseAddr
Note: The message buffer register number m in the register symbols has 2 digits, for example,
C0MDATA01m = C0MDATA0100 for m = 0.
