На выходе должен увидеть прямоугольные бесконечные импульсы длительностью в один цикл, а с помощью логического анализатора вижу, что кристалл перезапускается каждые 470,35 мкс.
Не могу понять почему?. А так же вижу, при запуске высокий уровень на обоих выходах. Хотя вроде все делаю чтобы опустить в ноль выходы.
