Does anyone know "automatic cooking" modes in microwaves?

I decided to finally try one and was supposed to leave raw pork in there for 12 minutes, but after 4 minutes I can smell something burned from my bedroom. As I open the door to the kitchen, it was all foggy and it seemed like something almost caught fire in the microwave. But since this only happened in automatic cooking mode, now I wonder what was activated in there additionally that suddenly it was almost burning?

Any experts here? 👀
