NVMC driver wait_for_flash_ready

[JeanMBoones]

I have a question about the wait_for_flash_ready routine in the nrf_nvmc.c file.

    static inline void wait_for_flash_ready(void)
{
    while (NRF_NVMC->READY == NVMC_READY_READY_Busy) {;}
}

Can you tell me if this particular while loop can ever get stuck? Does it timeout after a certain time? If so, is there any way to detect that this timed out and the NVM controller was not able to complete the operation?

Yes. But could there be a scenario when this statement NRF_NVMC->READY == NVMC_READY_READY_Busyis always true due to some error in the hardware i.e. it always thinks there is some activity going on. Wouldn't we get stuck in an infinite loop? What happens then?
