Hi.

First, I would like to ask about page erase time. As stated in RM (for STM32F303) it should last min. 20 ms to max. 40 ms. But I checked it with ETM profiler and the whole process of erase took only around 100 us. Do you have any idea why it could be that short?

Second, I would like to ask what happens, if reset occurs during page erase? Is it possible to say, how will this page look like after power on? Let say it was full of some data. After erase we know there are all FFs. But what, if reset occurs between that erase time.

Thanks
