+  * @brief   FLASH HAL module driver.
+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the internal FLASH memory:
+  *           + Program operations functions
+  *           + Memory Control functions 
+  *           + Peripheral State functions
+  *

+  ==============================================================================
+                        ##### FLASH peripheral features #####
+  ==============================================================================
+           
+  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses 
+       to the Flash memory. It implements the erase and program Flash memory operations 
+       and the read and write protection mechanisms.
+      
+  [..] The Flash memory interface accelerates code execution with a system of instruction
+      prefetch. 
+
+  [..] The FLASH main features are:
+      (+) Flash memory read operations
+      (+) Flash memory program/erase operations
+      (+) Read / write protections
+      (+) Prefetch on I-Code
+      (+) Option Bytes programming
+      
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]                             
+      This driver provides functions and macros to configure and program the FLASH 
+      memory of all STM32F0xx devices. These functions are split in 3 groups:
+    
+      (#) FLASH Memory I/O Programming functions: this group includes all needed
+          functions to erase and program the main memory:
+        (++) Lock and Unlock the FLASH interface
+        (++) Erase function: Erase page, erase all pages
+        (++) Program functions: half word and word
+    
+      (#) Option Bytes Programming functions: this group includes all needed
+          functions to manage the Option Bytes:
+        (++) Lock and Unlock the Option Bytes
+        (++) Erase Option Bytes
+        (++) Set/Reset the write protection
+        (++) Set the Read protection Level
+        (++) Program the user Option Bytes
+        (++) Program the data Option Bytes
+        (++) Launch the Option Bytes loader
+    
+      (#) Interrupts and flags management functions : this group 
+          includes all needed functions to:
+        (++) Handle FLASH interrupts
+        (++) Wait for last FLASH operation according to its status
+        (++) Get error flag status           
+
+  [..] In addition to these function, this driver includes a set of macros allowing
+       to handle the following operations:
+      
+      (+) Set the latency
+      (+) Enable/Disable the prefetch buffer
+      (+) Enable/Disable the FLASH interrupts
+      (+) Monitor the FLASH flags status
+
