+/* Function that handles firmware-driven enabling or disabling of APPROTECT on devices where it is supported.
+        If ENABLE_APPROTECT is defined, the FW will lock the fw branch of the APPROTECT mechanism,
+                            preventing it from being opened.
+        If ENABLE_APPROTECT_USER_HANDLING is defined, the FW will not write to the fw branch of the APPROTECT mechanism.
+                            This allows later stages of the fw to handle APPROTECT,
+                            for example to implement authenticated debug.
+        Otherwise, the fw branch state is loaded from UICR.
+
+         The same mechanism is implemented for SECURE APPROTECT, with the macros
+         ENABLE_SECURE_APPROTECT and ENABLE_SECURE_APPROTECT_USER_HANDLING. */
