Hi Marcin, If I read this correctly then a reset may be performed for several different conditions - values of different registers - for a VF as checked in a for loop. I am wondering if multiple resets could occur for the same VF within an iteration of the for loop - because more than one of the conditions is met. And, if so, is this ok?
