+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..] This driver provides functions to configure and program the FLASH memory
+ of all STM32F0xxx devices. It includes
+
+ (+) Set/Reset the write protection
+ (+) Program the user Option Bytes
+ (+) Get the Read protection Level
