Detailed Description

FLASH Memory Programming functions.

 ===============================================================================
                      FLASH Memory Programming functions
 ===============================================================================  

   The FLASH Memory Programming functions, includes the following functions:
    - void FLASH_DeInit(void);
    - void FLASH_Unlock(FLASH_MemType_TypeDef FLASH_MemType);
    - void FLASH_Lock(FLASH_MemType_TypeDef FLASH_MemType);
    - void FLASH_ProgramByte(uint32_t Address, uint8_t Data);
    - void FLASH_EraseByte(uint32_t Address);
    - void FLASH_ProgramWord(uint32_t Address, uint32_t Data);
    - uint8_t FLASH_ReadByte(uint32_t Address);
   
   Any operation of erase or program should follow these steps:

   1. Call the FLASH_Unlock(FLASH_MemType) function to enable the memory access

   2. Call the desired function to erase or program data

   3. Call the FLASH_Lock() function to disable the memory access 
     (it is recommended to protect the FLASH memory against possible unwanted operation)
