WebConsequently, software is expected to clear the flag in the EXTI_PR1 register to disable the wakeup request when the source of the wakeup is a configurable event. For direct events, the flag is located in the peripheral unit. These flags enable the software to find the cause of the wakeup. The wakeup indication is asserted when either the interrupt Webnoun. ˈklir-ˌkət. : an area of forest in which all the trees have been cut down.

WebQuite likely the issue here is that the ISR ends before the bus cycle for accessing the interrupt flag has completed. Just spending a bit more time in the ISR and clearing the flag as early as possible should help. You might also try if a synchronization barrier (DSB) after clearing the flag helps.

WebAs shown in Figure 2.1 (p. 4) each IRQ line can be triggered by one or more interrupt flags (IF). Normally these interrupt flags will be set by a hardware condition (e.g. timer overflow), but SW can also set and clear these directly by writing to the IFS (Interrupt Flag Set register) or IFC (Interrupt Flag Clear register).
