18. CAN Module

This document is under development and its contents are subject to change.

Table 18.1 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.

i = 0, 1

n = 0 to 15: the number of the slot
