Ни с ней, ни без нее не работает. Как я понимаю - сначала должен сконфигурироваться таймер, затем запуститься, а analogWrite просто запустит ШИМ на выходе, с учетом настроенных параметров. Но это не точно. Вернее я точно где-то ошибаюсь.
А без толку. Я только сейчас заметил, что у ТС в первом посте ссылка на то же самое, только не в пдф, а в онлайн. Похоже, это у него есть, но этого ему мало
