Can timers be accessed after advertisement starts?

Question

I am new to nrf52. 
 I want to configure TIMER1 as a counter. 
 However it does not count. I have added it after advertisement_init 
 Does the nrf52 have any such limitations? How to handle them?

I was finally able to get the TIMER working but with registers and not the drv. I really do not know what is wrong with the driver. uint32_t counter = 0 ; static void hfclk_config(void) // Select { ret_code_t err_code = nrf_drv_clock_init(); APP_ERROR_CHECK(err_code); nrf_drv_clock_hfclk_request(NULL); } static void counter_init() { // Initialize timer module. NRF_TIMER1->TASKS_STOP = 1; NRF_TIMER1->MODE = 2;// Low Power counter mode NRF_TIMER1->PRESCALER = 8; // Fhck / 2^8 //NRF_TIMER1->CC[0] = 62500; // 62500 - 1s NRF_TIMER1->BITMODE = (TIMER_BITMODE_BITMODE_24Bit << TIMER_BITMODE_BITMODE_Pos); NRF_TIMER1->TASKS_CLEAR = 1; } static void read_TIM(void) // Follow 3 steps. { NRF_TIMER1->TASKS_COUNT = 1; // Step 1 NRF_TIMER1->TASKS_CAPTURE[1] = 1 ; // Step 2. The TIMER implements one capture task for every available capture/compare register. //Every time the CAPTURE[n] task is triggered, the Counter value is copied to the CC[n] register. counter = NRF_TIMER1->CC[1]; // Step 3 while(counter < 10000) { NRF_TIMER1->TASKS_COUNT=1; NRF_TIMER1->TASKS_CAPTURE[1] = 1 ; // The TIMER implements one capture task for every available capture/compare register. //Every time the CAPTURE[n] task is triggered, the Counter value is //copied to the CC[n] register. counter = NRF_TIMER1->CC[1]; } NRF_TIMER1->TASKS_CLEAR = 1; } int main(void) { hfclk_config(); counter_init(); NRF_TIMER1->TASKS_START = 1; // Important for (;;) { read_TIM(); } }
