"is_clear" is not required since the type is a bool the "is" is implied in the the logical state so just "clear" will do. But re: my previous comment on having the ISR do the clear as is done in the VFE 480, I don't think this is_clear parameter is warranted. We want the calling function to request the rup_update() for the rup_update() function to wait on completion and the ISR() to do the clear once the RUP interrupt has been raised. At least I think that's how it should work - could you please experiment with your code for the flow - as it appears to match the VFE 480 logic. --- bod
