WebThe interrupt requests are merged using an OR function before connecting to the NVIC. (Note: this is specific to STM32 design). Each of the interrupt service (for each EXTI channel) need to clear their own pending status in the EXTI using EXTI_PR (pending register) to deassert the interrupt to NVIC. WebThis may even be a more general, non-timer specific problem, which demonstrates itself also in the bug from 2.10.2 in the current rev.3 STM32F4xx Errata. Below is a fragment which illustrates the problem; the capture is replaced by compare so that there is no need for external hardware to reproduce it.
