Data
Each message object can use from zero to eight data registers to hold data to
be transmitted or data received.
For receive message objects, these registers accept data during a reception.
For transmit message objects, write the data that is to be transmitted to these
registers. The number of data bytes must match the DLC field in the
CAN_MSG x CFG register. (For example, if CAN_MSG1DATA0,
CAN_MSG1DATA1, CAN_MSG1DATA2, and CAN_MSG1DATA3 contain data,
the DLC field in CAN_MSG1CFG must contain 04H.)
