Hey guys.

I'm working with an ultra sound piece for measuring the distance.

When i set the timer1 to count every 1 ms it works(i set PSC 59999 and ARR 1000 to get 1 second with 120M cpu clock.).

But when i set the PSC 11 and ARR 1 to get a 0.1 us interrupt its not correct and it doesn't count correctly. 

Do you know what is the problem?
