TIMSK &= ~(1<<TOIE2)
TCCR2 &= ~((1<<WGM21) | (1<<WGM20))
"TCCR2B &= ~(1<<WGM22))" эту строчку удалил не нашел описание в книжки
ASSR &= ~(1<<AS2);
tcnt2 = 252; // 16000000/31000/64=8 tcnt2=256-8=248.
TIMSK |= (1<<TOIE2)


Получилось написать прошивку для tiny2313 на асм. 12 каналов правда кварц хитрый нужен на 7.3728 иначе uart работает нестабильно. а так все работает на ура тока если яркость на 0 выставить в програме от chip'a то глючит.
думаю штуки 4 параллельно законектить и будет 48 каналов.

исходник... мож кому пригодится
