Perhaps I am not reading the input capture section for the s12p correctly. I cannot find the delaycount register. Does it not exist on the p version? This makes no sense-how can noise be filtered out say, if one was to connect the input capture pin to a camshaft or crankshaft sensor? Even with external filtering on this pin I have always seen noise and used the delay count to filter it out. Wasn't this derivative designed specifically for the small engine market?
