+ * @version V1.1.0
+ * @date 14-April-2017
+ * @brief Header file of CORTEX LL module.
+ @verbatim
+ ==============================================================================
+ ##### 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 @ref LL_mDelay and @ref 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)
+

+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The LL SYSTEM driver contains a set of generic APIs that can be
+ used by user:
+ (+) Some of the FLASH features need to be handled in the SYSTEM file.
+ (+) Access to DBGCMU registers
+ (+) Access to SYSCFG registers
