These registers contain the data to be sent or that has been received. In a CAN data frame, data
byte 0 is the first byte to be transmitted or received and data byte 7 is the last byte to be transmitted
or received. In CAN's serial bit stream, the MSB of each byte is transmitted first.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
