Is it possible to reset TIM3 Count register by hardware using an External Pin?

[ADesi.3]

Hello,

In my application I need to clear TIM 3 Counter on Rising Edge of an external Pin.

My target MCU is STM32C011

Is there any example available?

Thanks

That should do the trick.

Thanks for the answer.

This configuration is Edge sensitive or Level Sensitive?

I need the timer to stay Reset when the external signal is High

Thanks

Edge, see description of TIMx_SMCR.SMS in RM.

Gated mode is edge sensitive, but that does not reset the timer's counter. You may perhaps combine it with some interrupt which would provide the reset.
