+  * @version V1.3.2
+  * @date    26-June-2015
+  * @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 Errors 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 and cache lines.
+
+  [..] The FLASH main features are:
+      (+) Flash memory read operations
+      (+) Flash memory program/erase operations
+      (+) Read / write protections
+      (+) Prefetch on I-Code
+      (+) 64 cache lines of 128 bits on I-Code
+      (+) 8 cache lines of 128 bits on D-Code
+
+
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      This driver provides functions and macros to configure and program the FLASH
+      memory of all STM32F4xx devices.
+
+      (#) FLASH Memory IO Programming functions:
+           (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
+                HAL_FLASH_Lock() functions
+           (++) Program functions: byte, half word, word and double word
+           (++) There Two modes of programming :
+            (+++) Polling mode using HAL_FLASH_Program() function
+            (+++) Interrupt mode using HAL_FLASH_Program_IT() function
+
+      (#) Interrupts and flags management functions :
+           (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
+           (++) Wait for last FLASH operation according to its status
+           (++) Get error flag status by calling HAL_SetErrorCode()
+
+    [..]
+      In addition to these functions, this driver includes a set of macros allowing
+      to handle the following operations:
+       (+) Set the latency
+       (+) Enable/Disable the prefetch buffer
+       (+) Enable/Disable the Instruction cache and the Data cache
+       (+) Reset the Instruction cache and the Data cache
+       (+) Enable/Disable the FLASH interrupts
+       (+) Monitor the FLASH flags status
