You can refer to the PSoC Creator User Guide for information regarding PSoC Creator, Generated Source, etc. PSoC Creator is IEC 9899 compliant and the deviations are mentioned in the User Guide as well. Let me check internally if PSoC Creator is validated for IEC 62304.
You can refer to the PSoC Creator Release Notes for the known issues with the corresponding release version of PSoC Creator.
