Get PWM output state for interrupt purposes STM32F215

I'm working on STM32F215 and I generate a PWM output on TIM1. This signal is going to an other device.

For synchronization purposes on this signal, I would like to get the rising and falling edge of it.


My first thought is to link the PWM ouptut directly to a EXTI pin in order to get my edges interrupt.


I just begin working with Timer but I'm just there is a simple way to get those PWM informations.


Could you please help me with a code example/interrupt configuration ?


Thank you very much,
