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 (Window > Target Memory Views > Configuration Bits). 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 . Make any changes to the data in the window and then write changes back to the device by using the Program Configuration Bits icon .
