23.4.49 IF3DATA Register (offset = 150h) [reset = 0h]
IF3DATA is shown in Figure 23-67 and described in Table 23-62.
The data bytes of CAN messages are stored in the IF3 registers in the following order. In a CAN data
frame, Data 0 is the first, and Data 7 is the last byte to be transmitted or received. In CAN's serial bit
stream, the MSB of each byte will be transmitted first.
