I have been reading about code regions in the nrf reference manual and understood about CLENR0 and how to use it. I have however, two questions
-
What is Pre Programmed factory content? There is register to find whether the PPFC is present or not but what exactly is this content and where is it located.
-
Why is CLENR0 located in two places : FICR and UICR and which one overrides which if there are different values for both
Thanks
