16.2 Arm GCC Toolchain
Most configuration bits are contained in device GPNVM bits. Specifically, the GPNVM0 represents the Security bit.
To program code protection configuration bits, Lock bits are used.
To program configuration bits, use the Configuration Bits window ( ). When you first open the Configuration Bits window, the data will need to be red, meaning you need to read from device memory. Use the Read Configuration Bits icon
