AVR Studio 4.13 SP1 557, Simulation bug no interrupt called Опции

[Alex_Elov]

Привет всем!

Вообщем багу нашел в симуляторе AVR Studio. Написал на Atmel. Ответили. Вот эту инфу и привожу может кому поможет, сам день потерял..

Dear Mr ...

Thank you for your report. Bug reports are highly appreciated. I have tested and verified the odd behaviour and reported it. We are now working on designing a Simulator II and hopefully this bug will be fixed in this version before it is released. I don't have any release date for ATmega16 support in sim II so in the mean time I suggest you try on chip debugging which will give a more reliable result.
