TwinCAN Module
21.3.3 Register Table
Table 21-10 shows the system registers related to the TwinCAN module. It summarizes
the addresses and reset values. In order to simplify the kernel description, the prefix
‘CAN_’ is added only in this register list.
The start address for the TwinCAN module is 20’0000_H, the register offsets (relative to
this address) are given in the TwinCAN kernel description. See Figure 21-27. A full
register listing of all CAN registers is provided in register table section and in the system
book.

1) The 8-bit short addresses are not available for the TwinCAN module kernel registers.
2) In the XC161 device, the CAN interrupt node 7 is shared with the SDLM interrupt 1. In order to avoid
mismatches if the CAN interrupt 7 is used by the TwinCAN module, the SDLM interrupt 1 should be mapped
to a common SDLM interrupt 0 (see register SDLM_PISEL).
