haakonsh Makes no sense. But this may happen due to async (event driven) programming. The question was, what happens if someone tries to stop a stopped timer.

[haakonsh]

Oh in that case nothing should happen as another 'rtc1_stop' will be scheduled, and this function can safely be called multiple times. 

See line 176 of app_timer.c: 

/**@brief Function for stopping the RTC1 timer.
*/
static void rtc1_stop(void)
{
NVIC_DisableIRQ(RTC1_IRQn);

NRF_RTC1->EVTENCLR = RTC_EVTEN_COMPARE0_Msk;
NRF_RTC1->INTENCLR = RTC_INTENSET_COMPARE0_Msk;

NRF_RTC1->TASKS_STOP = 1;
nrf_delay_us(MAX_RTC_TASKS_DELAY);

NRF_RTC1->TASKS_CLEAR = 1;
m_ticks_latest = 0;
nrf_delay_us(MAX_RTC_TASKS_DELAY);

m_rtc1_running = false;
}
