6 Summary

This document introduces the implementation of a CAN to SPI bridge, including structure, function definition, interface usage and application aspects. The MSPM0 device can act as a translator between the CAN and the SPI, which allows the bridge to send and receive information on one interface and receive and send the information on the other interface.
