External IO port interrupt, the initial setting is the rising edge trigger interrupt, but when the io port level is kept at 1.2V, the interrupt will not be triggered all the time. Have you encountered this problem?

There is no clear interrupt flag.

Turn off the interrupt after triggering, and turn on the interrupt after the processing is completed. .

1. You'd better refer to the history to check whether the program setting is correct and whether it is set to level trigger
2. Unless afterwards, the signs should be cleaned up in time,
