10 Conclusion

This application report describes many of the key features change and new modules in the MSP430FR4xx family compared to the MSP430F2xx family. While this document is intended to be comprehensive, there may be minor differences between the F2xx and the FR4xx families that have not been covered here. For details of a given device, the device-specific data sheet is always the best source of information. For module functionality and use, see the MSP430FR4xx and MSP430FR2xx family user's guide. For any bugs and workarounds in the FR4xx family devices, see the device-specific errata sheet.
