    [..] FLASH_Interface configuration_Functions, includes the following functions:
       (+) void FLASH_SetLatency(uint32_t FLASH_Latency):
    [..] To correctly read data from Flash memory, the number of wait states (LATENCY) 
     must be correctly programmed according to the frequency of the CPU clock (HCLK) 
    [..]
        +--------------------------------------------- +
        |  Wait states  |   HCLK clock frequency (MHz) |
        |---------------|------------------------------|
        |0WS(1CPU cycle)|       0 < HCLK <= 24         |
        |---------------|------------------------------|
        |1WS(2CPU cycle)|       24 < HCLK <= 48        |
        +----------------------------------------------+

       (+) void FLASH_PrefetchBufferCmd(FunctionalState NewState);

     All these functions don't need the unlock sequence.
