How to reset timer counter value once captured

I have a timer set up with a capture register which loads the counter value on a rising edge with the code below. However the counter value keeps increasing until overflow (not when counter value loaded into capture register) so I cannot measure frequency of input signal. Therefore I want to reset the counter register (CNT) automatically (in hardware, not manually clearing it in a interrupt) once value loaded into capture register (CCR) so I can read the CCR to get frequency.
