Figure 4-12. eCAN-B Memory Map
The CAN registers listed in Table 4-7 are used by the CPU to configure and control the CAN controller
and the message objects. eCAN control registers only support 32-bit read/write operations. Mailbox RAM
can be accessed as 16 bits or 32 bits. 32-bit accesses are aligned to an even boundary.
