Hi Kim,

Think this post might be of interest:

You should be able to write 0xFFFFFF00 to following register NRF_UICR->APPROTECT to protect the code in the flash.

Edit:

You could also as Nguyen mentioned protect the application directly, by adding --rbp ALL when flashing with nrfjprog

You can use nrfjprog to enable read back protection option. It is part of the Nordic command line tools. You can download it directly from nordicsemi.com
