==============================================================================
                   ##### 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 DDL_mDelay and DDL_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)
