I am using STM32F7(216MHz). When I test input capture of TIM2 and TIM11, rising edge  interrupt was missimg some time. The callback function is not call by interrupt at the ratuo about 1 of 100. Input signal frequency is 450kHz.

 

What should I do to captue input signal without missing interrupt function call.

 

Thanks.
