You can write to flash and get the written values back. That does the fds library for you. There are some examples around the forum.

If by reset you mean reset without power cycle, search the forum for "memory retention" keywords. There is plenty of topics about that. If you want to power-cycle, use non-volatile memory as @Moritz suggested…

I am not sure whether I should open a new question and will describe what my problem really is: I need to disable softdevice for my application to send a uninterrupted pulse trains on a general-purpose output pin. A sd_softdevice_disable() is issued before I send the pulse trains and sd_softdevice_enable(clock_source, NULL) is issued to re-enable softdevice. But I found that the chip seems to be reset. So my solution might be how to re-enable softdevice.
