Thanks Andreas that is helpful.

I especially note your mention of GID and GIE. Currently the C compiler generates these around a change of arithmetic mode (floating point vs integer). I'm not sure why. It could only protect against an interrupt service routine making a permanent change to CONFIG and that change getting lost by the user code changing CONFIG. I can't offhand think of any reason why a randomly happening ISR would want to make a permanent change to CONFIG. Some change of a timer mode?!

Off topic, I hope everyone here has restful holidays which are fun and a complete break from work.

Thanks Tim!

Not sure what our reasoning was?? I can check in with @amylaar who wrote the GCC compiler code. I think this might have been an old "safety measure" that we didn't need in the end. Can you add an issue to gcc? (I would be happy to do it myself, but you should have the honors:-) Note that there is no such code in the elib register read/write function call.

Have a great holiday everyone!
