2) Тактируйте на 16 МГц;
3) Смешайте сигнал с 3-й и 17-й ноги при помощи пары резисторов;
4) Подайте на видеовход ближайшего телека;
5) Узрите Явление :)
ЗЫ: построчный сигнал гашения лежит прямо в видеопамяти, что в корне бессмысленно. Да и не нужна она как таковая -- всякие графики лучше "на ходу" генерить и не тратить оперативу.
ЗЫЫ: на прерываниях это еще бы могло параллельно решать какие-то другие задачи, т. к. за вывод отдувается в основном порт.
ЗЫЫЫ: диаграммы и построения сигнала для разных тактовых частот могу выложить, если интересно.
