Hello what is the structure for writing specific ISR for different on chip peripherals?
Your sample code for that incredible machine of yours will show you how. Jack Sprat wrote not long ago: "I have also noticed that you are not averse to using language that would be considered blasphemy by at least one of the major global religions". So you see Jack, I CAN glorify a processor core without the sin of blasphemy after all :-) but I admit having to bite my tongue!
