Хорошая штука, заточенная именно под цели управления (индуктивной нагрузкой).
Какой нафиг АВР с ней может сравниться?

Одних ШИМ регистров семь штук, да плюс таймер для синхронизации внешних событий, не считая пары универсальных таймеров...
А в меге - максимум три нормальных таймера, универсальных... - голытьба!
