How to secure the nRF52's flash from read back with JLink Commander

[Michael]

Hello!

I would like to program the nRF52 using the JLink Commander and protect it afterwards. Which register do I need to manipulate?

Thanks and kind regards,

Michael

You need to set PALL (0xFFFFFF00) to UICR->APPROTECT.
