This will protect the memory content of the device, as it will only be possible to debug and access the memory after performing an erase all (recover) operation.</p> <p>However, there is no mechanism to prevent a recover operation on these devices. The nRF53 series has an ERASEPROTECT mechanism, but this does not exist in the nRF 52 series devices.</p><div style="clear:both;"></div>
