Timer interrupts synchronization in Cortex M4

Hi,

I am working on Cortex M4 based Microcontroller.

I have one timer(TIM0) running and when it gets restarted, GPIO pin is set. I have one more timer (TIM1) running separately and it sets another GPIO pin.

Now I would like to synchronize these two timer interrupts (TIM0 and TIM1). 

Anyone has idea on how to implement it?

Thanks in advance!!
