19.2 CANi Message Box (i = 0, 1)
Table 19.1 shows the memory mapping of the CANi message box.
It is possible to access to the message box in byte or word.
Mapping of the message contents differs from byte access to word access. Byte access or word access can
be selected by the MsgOrder bit of the CiCTLR register.
