5 Summary

This document begins with an overview of the CAN bus and the features of MCAN module integrated in the MSPM0 MCU. The application note details how to use Sysconfig to configure the CAN module, so that users can adjust related parameters to meet application requirements. This document briefly describes the demo example related to MCAN module provided in the MSPM0 SDK. Finally, some common debugging issues and relevant debugging suggestions from the software and hardware aspects are introduced.
