Why counter of timer not repeat

[Giang]

Hi all , I using timer 0 to count from 0 to max value 32bit . In my code : 

    while (1)
    {
					NRF_TIMER0->TASKS_CAPTURE[1] = 1;	
					counter = NRF_TIMER0->CC[1];
					if(counter==100000)
					{
						nrf_gpio_pin_toggle(LED_1);
					}
	}

If I using NRF_TIMER0->TASKS_CAPTURE[1] = 1; for save counter value to CC register . It run once time and don't reset to 0 after overflow . If I using NRF_TIMER0->TASKS_CLEAR = 1; counter will be 0 . Why not reset to 0 ? Please explain to me . Thank

Hi,

I'm not sure if I understand your question. When exactly would you like the timer to reset to 0? If your counter register reaches 32 bit max value (0xFFFFFFFF) then it has 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?
