CAN0 Message Box

Table 1.19.1 shows the memory mapping of the CAN0 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 C0CTLR register.
