TIMER 3 OUTPUT CHANNEL TRIGGER

Hello, 

 I am using NUCLEO-F429ZI. I want to use TIMER 3 for timing trigger. So I set channel 1 as output channel and ocmode is TIM_OCMODE_ACTIVE . The timing is perfect, but it looks like I only can generate a low pulse. I would like use rising edge to trigger some other digital output, but timer 3 interrupt can't be triggered. It seems I need another digital pin "A" as the input of timer 3 output channel 1 and use "A" to trigger interrupt event. Is it possible to void extra digital pin to trigger some event when timer channel set to TIM_OCMODE_ACTIVE.

 

Regards,
