******************************************************************************

* @author MCD Application Team
* @version V4.2.0
* @date 31-March-2017
* @brief CMSIS STM32F1xx Device Peripheral Access Layer Header File.
*
* The file is the unique include file that the application programmer
* is using in the C source code, usually in main.c. This file contains:
* - Configuration section that allows to select:
* - The STM32F1xx device used in the target application
* - To use or not the peripheral’s drivers in application code(i.e.
* code will be based on direct access to peripheral’s registers
* rather than drivers API), this option is controlled by
* "#define USE_HAL_DRIVER"
*

==============================================================================
##### 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)
