hi, i am using NRF52 custom board. i want to provide serial number to each board, which i want to read or write any time using my firmware. if i erase the bord it should not erase the serial number registers is it possible to make it happen. please give me suggestion. Currently, i am using UICR registers to read and write serial number in it. but if i erase chip. these registers also erasing.
Thankyou.
