Store configuration settings on nrf51

[helpme]

I have a nrf51-dk. I would like to the pincode to be stored in some configuration settings which is written in non-volatile memory. I do not want the pincode to be hard-coded in the source code. Can this be done on nrf51 chip? What are some good examples that I can refer to?

Try Flash Data Storage (fds) instead, it provides a higher level of abstraction and other nice features over pstorage.
