In the nrf51 series reference manual section 12.1.9 it states that there is hardware protection that prevents write instructions from being executed and that there is more information in the NVMC chapter. I read through that chapter and found no information about the hardware protection. Is there more information in a separate file that I could reference?
Currently I'm using the pstorage API to store device settings periodically and I don't want it to happen when I'm below the POF warning level. Will the hardware protection prevent this from occurring, and will it also prevent clears from happening?
