4 Appendix - FMEDA to Diagnostic API Mapping

This appendix maps the hardware element failure modes identified in the SAM C21 FMEDA to the diagnostic library’s API functions that can be used to help implement the safety mechanisms described in the SAM C21 Safety Manual for those failure modes. The DMs are either a responsibility of diagnostic library software or "none" which denotes that it is not the responsibility of the software.
