On the nRF51, there are 5 OVERRIDE registers (0-4) in the radio module.
What do those registers do and when should they be used? The FRM was not clear about them.
From what I can see the scenario where you have a serialized app running from a separate CPU and how to do firmware update on that is not discussed anywhere on the Nordic...
