16.11.2.2 Operation From a Debug Adapter
Debug adapters must access the DSU registers in the external address range 0x100-0x2000. If the device is protected by the Code Protect bit, accessing the first 0x100 bytes causes the system to return an error. See Intellectual Property Protection from Related Links.
When the device debug is locked through Secure Device, other than DSU external address range, Flash Controller registers, eFuse controller registers and Flash Memory addresses are placed under MEM-AP permissible address range to allow programming.
