DMA Timer Overflow

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.
