Hi,

I never used chip-wide resets but I assume this input is not visible to firmware but to hardware only(I am not sure, any advice...)

You can emulate an internal reset through logic e.g. a counter going up from 0 to 15 and stop then generate your reset on count values. Make sure the counter powers up at zero and that it is not optimised off.
