NEC IR Decoder, Распознование пульта NEC Опции

[dvm11111111]

Доброго всем времени суток. Вот решил пульт с кодировкой NEC прикрутить к 88 меге. Первоисходник http://www.mcselec.com/index.php?option=co...3&Itemid=57 на BASCOM. Переделал под WINAVR, НО ВОТ РАБОТАЕТ ЭТО ВСЕ КАК-ТО НЕПОНЯТНО. Исходник прилагаю мега работает от внутреннего 8МГц, приемник на INT0, светодиод на POTB.1. ГУРУ посмотрите что не так на первый взгляд.
