+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+    The LL CORTEX driver contains a set of generic APIs that can be
+    used by user:
+      (+) SYSTICK configuration used by LL_mDelay and LL_Init1msTick
+          functions
+      (+) Low power mode configuration (SCB register of Cortex-MCU)
+      (+) MPU API to configure and enable regions
+          (MPU services provided only on some devices)
+      (+) API to access to MCU info (CPUID register)
+      (+) API to enable fault handler (SHCSR accesses)
