That why it’s called a reference. They can absolutely state that you were terminated and whether they would hire you again. Most don’t want to open up the door to litigation, so they don’t share too much to save the time and money (they would almost certainly win short of something truly egregious by them which is almost impossible to prove). I’d be more concerned about how you will speak to the situation that lead to the letting go. We all have bumps in the road, most people are reasonable. Good luck.
