DMA Timer Overflow

Hi,

 

I am using MCF52254 coldfire. I have a problem with DMA Timer. Basically, I am using DMA Timer 0 for input capture and also use it for internal timing purpose.

 

But there is one problem. When the timer overflows, how do I know that the counter restarted.

 

I know that I can use GPT#3 for this purpose but that is 16-bit timer only and it overflows too quickly.

 

Any suggestion will be helpful.

 

Regards.
