WebIt is, but only if you are executing the ISR. But from non-interrupt context, you have to explicitly clear also the NVIC pending bit (see NVIC_ICPRx register). This is what I quoted above: if the interrupt kicks in, it clears this bit in hardware; but if it's not the interrupt context, you have to do it yourself. So the procedure is:
