In my code : If I using NRF_TIMER0-&gt;TASKS_CAPTURE[1] = 1; for save counter value to CC register . It run once time and don&#39;t reset to 0 after overflow .

If your counter register reaches 32 bit max value (0xFFFFFFFF) then it <em>has</em> to reset to 0. Do you want to reset the counter register when your counter has counted to 100000? Can you show us the code that you use to initialize the counter?</p><div style="clear:both;"></div>
