How to clean external interrupt Flag

[digi55]

Hi, @board707
How do I clear the flag when an external interrupt occurs on the STM32F411 processor?
After the interrupt ISR is called, I need to clear the corresponding Flag.
If this flag is not cleared, the interrupt will operate unstable and sometimes even cause deadlocks.
Since Roger Clark's libmaple is now closed, I couldn't find any explanation anywhere.
Do you have any advice?

Hi @digi55
I apologize for the delay in replying. Unfortunately, I can hardly help. I don't know the exact answer to the question, and I don't have enough time to search the documentation now.

Since Roger Clark's libmaple is now closed, I couldn't find any explanation anywhere.

I would like to say that the end of support for the Clark's distribution does not mean that there is no way to solve problems. All the details of working with each STM32 chip are described in the datasheet, and if something is missing in Clark's code, you can add it yourself. Despite the fact that Clark and his colleagues have stopped updating the repo, they accept pull requests written by others. I have already had to make adjustments to the Clark project, adding features to the code that were not there initially.

Thank you, for your answer.
