+ * @author MCD Application Team
+ * @version V1.0.0RC2
+ * @date 04-February-2014
+ * @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
+ *
+ @verbatim
+ ==============================================================================
+ ##### 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
