Do any of the nRF Connect BLE example use the UICR for anything? Does the library?

This should be a quick question. I really am just wondering if any part of the nRF Connect BLE library or examples use the UICR space? 

The library is more the question, since there isn't any source to examine.

Hi,

 

This should be a quick question. I really am just wondering if any part of the nRF Connect BLE library or examples use the UICR space? 

I suspect you are asking about the UICR.OTP region:

https://docs.nordicsemi.com/bundle/ps_nrf5340/page/chapters/uicr/doc/uicr.html#register.OTP

 

This is not directly used by NCS.

 

Kind regards,

Thanks for the answer. Actually, it enlightened me to a situation I was not aware of. 

I was actually wondering about the CUSTOMER register space of the nrf52840 UICR ( UICR — User information configuration registers  ) .
Your response has led me to the knowledge that that nrf5430 model CPU doesn't have that feature. Kind of an odd choice, but maybe it didn't fit in the CPU design (M33 core vs M4 using silicon differently).
In any case. The fact that not all models have this feature leads me to believe that it wouldn't be used.
