I encountered a problem when debugging the STOP mode. I used the GPIO interrupt to enter the STOP mode and also used the GPIO interrupt to wake up
But if you enter STOP mode directly in the GPIO interrupt function, you cannot wake up
If the flag bit is set in the GPIO interrupt, the while detection enters the STOP mode in the main function, you can wake up
Excuse me, can I enter the STOP mode during interrupt processing?

Does it have anything to do with this?

In the main loop to stop, before entering the stop, hang the corresponding IO to the corresponding interrupt line.

Try not to enter the stop mode in the interrupt. In the main loop mode, enter the stop mode
1. Because the following program needs to be executed after waking up, try to enter the stop mode in the main loop
2. After waking up from stop mode, reconfigure the clock
