+  *     - EV8_2 means that the data has been physically shifted out and output

+  *     Using EV8_2 leads to a slower communication but ensure more reliable test.

+  *        In this case the communication may be slower.

+ ===============================================================================
+                          I2C State Monitoring Functions
+ ===============================================================================
+  This I2C driver provides three different ways for I2C state monitoring
+  depending on the application requirements and constraints:
+         
+   
+     1. Basic state monitoring (Using I2C_CheckEvent() function)
+     -----------------------------------------------------------
+        It compares the status registers (SR1 and SR2) content to a given event
+        (can be the combination of one or more flags).
+        It returns SUCCESS if the current status includes the given flags 
+        and returns ERROR if one or more flags are missing in the current status.
+
+          - When to use
+             - This function is suitable for most applications as well as for startup 
+               activity since the events are fully described in the product reference 
+               manual (RM0090).
+             - It is also suitable for users who need to define their own events.
+
+          - Limitations
+             - If an error occurs (ie. error flags are set besides to the monitored 
+               flags), the I2C_CheckEvent() function may return SUCCESS despite 
+               the communication hold or corrupted real state. 
+               In this case, it is advised to use error interrupts to monitor 
+               the error events and handle them in the interrupt IRQ handler.
+         
+     Note 
+         For error management, it is advised to use the following functions:
+           - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+           - I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
+             Where x is the peripheral instance (I2C1, I2C2 ...)
+           - I2C_GetFlagStatus() or I2C_GetITStatus()  to be called into the 
+             I2Cx_ER_IRQHandler() function in order to determine which error occurred.
+           - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd() 
+             and/or I2C_GenerateStop() in order to clear the error flag and source 
+             and return to correct  communication status.
+             
+ 
+     2. Advanced state monitoring (Using the function I2C_GetLastEvent())
+     -------------------------------------------------------------------- 
+        Using the function I2C_GetLastEvent() which returns the image of both status 
+        registers in a single word (uint32_t) (Status Register 2 value is shifted left 
+        by 16 bits and concatenated to Status Register 1).
+
+          - When to use
+             - This function is suitable for the same applications above but it 
+               allows to overcome the mentioned limitation of I2C_GetFlagStatus() 
+               function.
+             - The returned value could be compared to events already defined in 
+               this file or to custom values defined by user.
+               This function is suitable when multiple flags are monitored at the 
+               same time.
+             - At the opposite of I2C_CheckEvent() function, this function allows 
+               user to choose when an event is accepted (when all events flags are 
+               set and no other flags are set or just when the needed flags are set 
+               like I2C_CheckEvent() function.
+
+          - Limitations
+             - User may need to define his own events.
+             - Same remark concerning the error management is applicable for this 
+               function if user decides to check only regular communication flags 
+               (and ignores error flags).
+      
+ 
+     3. Flag-based state monitoring (Using the function I2C_GetFlagStatus())

+     
+      Using the function I2C_GetFlagStatus() which simply returns the status of 
+      one single flag (ie. I2C_FLAG_RXNE ...). 
+
+          - When to use
+             - This function could be used for specific applications or in debug 
+               phase.
+             - It is suitable when only one flag checking is needed (most I2C 
+               events are monitored through multiple flags).
+          - Limitations: 
+             - When calling this function, the Status register is accessed. 
+               Some flags are cleared when the status register is accessed. 
+               So checking the status of one Flag, may clear other ones.
+             - Function may need to be called twice or more in order to monitor 
+               one single event.

+ ===================================================================      
+                 ##### How to use this driver #####
+ =================================================================== 
+ [..]
+   (#) Enable the CRYP controller clock using 
+       RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_CRYP, ENABLE); function.
+  
+   (#) Initialise the CRYP using CRYP_Init(), CRYP_KeyInit() and if needed 
+       CRYP_IVInit(). 
+  
+   (#) Flush the IN and OUT FIFOs by using CRYP_FIFOFlush() function.
+  
+   (#) Enable the CRYP controller using the CRYP_Cmd() function. 
+  
+   (#) If using DMA for Data input and output transfer, activate the needed DMA 
+       Requests using CRYP_DMACmd() function 
+  
+   (#) If DMA is not used for data transfer, use CRYP_DataIn() and  CRYP_DataOut() 
+       functions to enter data to IN FIFO and get result from OUT FIFO.
+  
+   (#) To control CRYP events you can use one of the following two methods:
+       (++) Check on CRYP flags using the CRYP_GetFlagStatus() function.  
+       (++) Use CRYP interrupts through the function CRYP_ITConfig() at 
+            initialization phase and CRYP_GetITStatus() function into interrupt 
+            routines in processing phase.
+         
+   (#) Save and restore Cryptographic processor context using CRYP_SaveContext() 
+       and CRYP_RestoreContext() functions.     
+  
+  
+ *** Procedure to perform an encryption or a decryption ***
+ ========================================================== 
+  
+ *** Initialization ***
+ ====================== 
+ [..] 
+   (#) Initialize the peripheral using CRYP_Init(), CRYP_KeyInit() and CRYP_IVInit 
+       functions:
+       (++) Configure the key size (128-, 192- or 256-bit, in the AES only) 
+       (++) Enter the symmetric key 
+       (++) Configure the data type
+       (++) In case of decryption in AES-ECB or AES-CBC, you must prepare 
+            the key: configure the key preparation mode. Then Enable the CRYP 
+            peripheral using CRYP_Cmd() function: the BUSY flag is set. 
+            Wait until BUSY flag is reset : the key is prepared for decryption
+       (++) Configure the algorithm and chaining (the DES/TDES in ECB/CBC, the 
+            AES in ECB/CBC/CTR) 
+       (++) Configure the direction (encryption/decryption).
+       (++) Write the initialization vectors (in CBC or CTR modes only)
+  
+   (#) Flush the IN and OUT FIFOs using the CRYP_FIFOFlush() function
+  
+  
+  *** Basic Processing mode (polling mode) *** 
+  ============================================  
+  [..]
+    (#) Enable the cryptographic processor using CRYP_Cmd() function.
+  
+    (#) Write the first blocks in the input FIFO (2 to 8 words) using 
+        CRYP_DataIn() function.
+  
+    (#) Repeat the following sequence until the complete message has been 
+        processed:
+  
+        (++) Wait for flag CRYP_FLAG_OFNE occurs (using CRYP_GetFlagStatus() 
+            function), then read the OUT-FIFO using CRYP_DataOut() function
+            (1 block or until the FIFO is empty)
+  
+         (++) Wait for flag CRYP_FLAG_IFNF occurs, (using CRYP_GetFlagStatus() 
+            function then write the IN FIFO using CRYP_DataIn() function 
+            (1 block or until the FIFO is full)
+  
+    (#) At the end of the processing, CRYP_FLAG_BUSY flag will be reset and 
+          both FIFOs are empty (CRYP_FLAG_IFEM is set and CRYP_FLAG_OFNE is 
+          reset). You can disable the peripheral using CRYP_Cmd() function.
+  
+ *** Interrupts Processing mode *** 
+ ==================================
+ [..] In this mode, Processing is done when the data are transferred by the 
+      CPU during interrupts.
+  
+    (#) Enable the interrupts CRYP_IT_INI and CRYP_IT_OUTI using CRYP_ITConfig()
+        function.
+  
+    (#) Enable the cryptographic processor using CRYP_Cmd() function.
+  
+    (#) In the CRYP_IT_INI interrupt handler : load the input message into the 
+         IN FIFO using CRYP_DataIn() function . You can load 2 or 4 words at a 
+         time, or load data until the IN FIFO is full. When the last word of
+         the message has been entered into the IN FIFO, disable the CRYP_IT_INI 
+         interrupt (using CRYP_ITConfig() function).
+  
+    (#) In the CRYP_IT_OUTI interrupt handler : read the output message from 
+         the OUT FIFO using CRYP_DataOut() function. You can read 1 block (2 or 
+         4 words) at a time or read data until the FIFO is empty.
+         When the last word has been read, INIM=0, BUSY=0 and both FIFOs are 
+         empty (CRYP_FLAG_IFEM is set and CRYP_FLAG_OFNE is reset). 
+         You can disable the CRYP_IT_OUTI interrupt (using CRYP_ITConfig() 
+         function) and you can disable the peripheral using CRYP_Cmd() function.
+  
+ *** DMA Processing mode *** 
+ ===========================
+ [..] In this mode, Processing is done when the DMA is used to transfer the 
+      data from/to the memory.
+  
+    (#) Configure the DMA controller to transfer the input data from the 
+         memory using DMA_Init() function. 
+         The transfer length is the length of the message. 
+         As message padding is not managed by the peripheral, the message 
+         length must be an entire number of blocks. The data are transferred 
+         in burst mode. The burst length is 4 words in the AES and 2 or 4 
+         words in the DES/TDES. The DMA should be configured to set an 
+         interrupt on transfer completion of the output data to indicate that 
+         the processing is finished. 
+         Refer to DMA peripheral driver for more details.  
+  
+     (#) Enable the cryptographic processor using CRYP_Cmd() function. 
+         Enable the DMA requests CRYP_DMAReq_DataIN and CRYP_DMAReq_DataOUT 
+         using CRYP_DMACmd() function.
+  
+     (#) All the transfers and processing are managed by the DMA and the 
+         cryptographic processor. The DMA transfer complete interrupt indicates 
+         that the processing is complete. Both FIFOs are normally empty and 
+         CRYP_FLAG_BUSY flag is reset.

+ [..] This section provides functions allowing to configure the CRYP Interrupts and 
+      to get the status and Interrupts pending bits.
+
+ [..] The CRYP provides 2 Interrupts sources and 7 Flags:
+
+ *** Flags : ***
+ ===============
+ [..] 
+   (#) CRYP_FLAG_IFEM :  Set when Input FIFO is empty. This Flag is cleared only
+       by hardware.
+      
+   (#) CRYP_FLAG_IFNF :  Set when Input FIFO is not full. This Flag is cleared 
+       only by hardware.
+
+
+   (#) CRYP_FLAG_INRIS  : Set when Input FIFO Raw interrupt is pending it gives 
+       the raw interrupt state prior to masking of the input FIFO service interrupt.
+       This Flag is cleared only by hardware.
+     
+   (#) CRYP_FLAG_OFNE   : Set when Output FIFO not empty. This Flag is cleared 
+       only by hardware.
+        
+   (#) CRYP_FLAG_OFFU   : Set when Output FIFO is full. This Flag is cleared only 
+       by hardware.
+                           
+   (#) CRYP_FLAG_OUTRIS : Set when Output FIFO Raw interrupt is pending it gives 
+       the raw interrupt state prior to masking of the output FIFO service interrupt.
+       This Flag is cleared only by hardware.
+                               
+   (#) CRYP_FLAG_BUSY   : Set when the CRYP core is currently processing a block 
+       of data or a key preparation (for AES decryption). This Flag is cleared 
+       only by hardware. To clear it, the CRYP core must be disabled and the last
+       processing has completed. 
+
+ *** Interrupts : ***
+ ====================
+ [..]
+   (#) CRYP_IT_INI   : The input FIFO service interrupt is asserted when there 
+      are less than 4 words in the input FIFO. This interrupt is associated to 
+      CRYP_FLAG_INRIS flag.
+
+      -@- This interrupt is cleared by performing write operations to the input FIFO 
+          until it holds 4 or more words. The input FIFO service interrupt INMIS is 
+          enabled with the CRYP enable bit. Consequently, when CRYP is disabled, the 
+          INMIS signal is low even if the input FIFO is empty.
+
+
+
+   (#) CRYP_IT_OUTI  : The output FIFO service interrupt is asserted when there 
+       is one or more (32-bit word) data items in the output FIFO. This interrupt 
+       is associated to CRYP_FLAG_OUTRIS flag.
+
+       -@- This interrupt is cleared by reading data from the output FIFO until there 
+           is no valid (32-bit) word left (that is, the interrupt follows the state 
+           of the OFNE (output FIFO not empty) flag).
+
+ *** Managing the CRYP controller events : ***
+ =============================================
+ [..] The user should identify which mode will be used in his application to manage 
+      the CRYP controller events: Polling mode or Interrupt mode.
+
+   (#) In the Polling Mode it is advised to use the following functions:
+       (++) CRYP_GetFlagStatus() : to check if flags events occur. 
+
+       -@@- The CRYPT flags do not need to be cleared since they are cleared as 
+            soon as the associated event are reset.

+       (++) CRYP_ITConfig()       : to enable or disable the interrupt source.
+       (++) CRYP_GetITStatus()    : to check if Interrupt occurs.

+ ===============================================================================
+                      ##### DAC Peripheral features #####
+ ===============================================================================
+    [..]        
+      *** DAC Channels ***
+      ====================  
+    [..]  
+    The device integrates two 12-bit Digital Analog Converters that can 
+    be used independently or simultaneously (dual mode):
+      (#) DAC channel1 with DAC_OUT1 (PA4) as output
+      (#) DAC channel2 with DAC_OUT2 (PA5) as output
+  
+      *** DAC Triggers ***
+      ====================
+    [..]
+    Digital to Analog conversion can be non-triggered using DAC_Trigger_None
+    and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register 
+    using DAC_SetChannel1Data() / DAC_SetChannel2Data() functions.
+    [..] 
+    Digital to Analog conversion can be triggered by:
+      (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
+          The used pin (GPIOx_Pin9) must be configured in input mode.
+  
+      (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8 
+          (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
+          The timer TRGO event should be selected using TIM_SelectOutputTrigger()
+  
+      (#) Software using DAC_Trigger_Software
+  
+      *** DAC Buffer mode feature ***
+      =============================== 
+      [..] 
+      Each DAC channel integrates an output buffer that can be used to 
+      reduce the output impedance, and to drive external loads directly
+      without having to add an external operational amplifier.
+      To enable, the output buffer use  
+      DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
+      [..]           
+      (@) Refer to the device datasheet for more details about output 
+          impedance value with and without output buffer.
+            
+       *** DAC wave generation feature ***
+       =================================== 
+       [..]     
+       Both DAC channels can be used to generate
+         (#) Noise wave using DAC_WaveGeneration_Noise
+         (#) Triangle wave using DAC_WaveGeneration_Triangle
+          
+          -@-  Wave generation can be disabled using DAC_WaveGeneration_None
+  
+       *** DAC data format ***
+       =======================
+       [..]   
+       The DAC data format can be:
+         (#) 8-bit right alignment using DAC_Align_8b_R
+         (#) 12-bit left alignment using DAC_Align_12b_L
+         (#) 12-bit right alignment using DAC_Align_12b_R
+  
+       *** DAC data value to voltage correspondence ***  
+       ================================================ 
+       [..] 
+       The analog output voltage on each DAC channel pin is determined
+       by the following equation: 
+       DAC_OUTx = VREF+ * DOR / 4095
+       with  DOR is the Data Output Register
+          VEF+ is the input voltage reference (refer to the device datasheet)
+        e.g. To set DAC_OUT1 to 0.7V, use
+          DAC_SetChannel1Data(DAC_Align_12b_R, 868);
+          Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
+  
+       *** DMA requests  ***
+       =====================
+       [..]    
+       A DMA1 request can be generated when an external trigger (but not
+       a software trigger) occurs if DMA1 requests are enabled using
+       DAC_DMACmd()
+       [..]
+       DMA1 requests are mapped as following:
+         (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be 
+             already configured
+         (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be 
+             already configured
+  
+      
+                      ##### How to use this driver #####
+ ===============================================================================
+    [..]          
+      (+) DAC APB clock must be enabled to get write access to DAC
+          registers using
+          RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
+      (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
+      (+) Configure the DAC channel using DAC_Init() function
+      (+) Enable the DAC channel using DAC_Cmd() function

+ ===============================================================================  
+    [..]       
+      The sequence below describes how to use this driver to capture image
+      from a camera module connected to the DCMI Interface.
+      This sequence does not take into account the configuration of the  
+      camera module, which should be made before to configure and enable
+      the DCMI to capture images.
+             
+      (#) Enable the clock for the DCMI and associated GPIOs using the following 
+          functions:
+          RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_DCMI, ENABLE);
+          RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
+  
+      (#) DCMI pins configuration 
+        (++) Connect the involved DCMI pins to AF13 using the following function 
+            GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_DCMI); 
+        (++) Configure these DCMI pins in alternate function mode by calling 
+            the function GPIO_Init();
+      
+      (#) Declare a DCMI_InitTypeDef structure, for example:
+          DCMI_InitTypeDef  DCMI_InitStructure;
+          and fill the DCMI_InitStructure variable with the allowed values
+          of the structure member.
+    
+      (#) Initialize the DCMI interface by calling the function
+          DCMI_Init(&DCMI_InitStructure); 
+    
+      (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
+          register to the destination memory buffer.
+    
+      (#) Enable DCMI interface using the function
+          DCMI_Cmd(ENABLE);
+                   
+      (#) Start the image capture using the function
+          DCMI_CaptureCmd(ENABLE);
+                   
+      (#) At this stage the DCMI interface waits for the first start of frame,
+          then a DMA request is generated continuously/once (depending on the
+          mode used, Continuous/Snapshot) to transfer the received data into
+          the destination memory. 
+     
+      -@-  If you need to capture only a rectangular window from the received
+           image, you have to use the DCMI_CROPConfig() function to configure 
+           the coordinates and size of the window to be captured, then enable 
+           the Crop feature using DCMI_CROPCmd(ENABLE);  
+           In this case, the Crop configuration should be made before to enable
+           and start the DCMI interface.

+ ===============================================================================
+
+ [..] External interrupt/event lines are mapped as following:
+   (#) All available GPIO pins are connected to the 16 external 
+       interrupt/event lines from EXTI0 to EXTI15.
+   (#) EXTI line 16 is connected to the PVD Output
+   (#) EXTI line 17 is connected to the RTC Alarm event
+   (#) EXTI line 18 is connected to the USB OTG FS Wakeup from suspend event
+   (#) EXTI line 19 is connected to the Ethernet Wakeup event
+   (#) EXTI line 20 is connected to the USB OTG HS (configured in FS) Wakeup event 
+   (#) EXTI line 21 is connected to the RTC Tamper and Time Stamp events
+   (#) EXTI line 22 is connected to the RTC Wakeup event
+
+                       ##### How to use this driver #####
+ ===============================================================================
+ 
+ [..] In order to use an I/O pin as an external interrupt source, follow steps 
+      below:
+   (#) Configure the I/O in input mode using GPIO_Init()
+   (#) Select the input source pin for the EXTI line using SYSCFG_EXTILineConfig()
+   (#) Select the mode(interrupt, event) and configure the trigger 
+       selection (Rising, falling or both) using EXTI_Init()
+   (#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init()
+
+ [..]     
+   (@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
+       registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

+   (#) Configure the GPIO pin(s) using GPIO_Init()
+       Four possible configuration are available for each pin:
+       (++) Input: Floating, Pull-up, Pull-down.
+       (++) Output: Push-Pull (Pull-up, Pull-down or no Pull)
+            Open Drain (Pull-up, Pull-down or no Pull). In output mode, the speed 
+            is configurable: 2 MHz, 25 MHz, 50 MHz or 100 MHz.
+       (++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull) Open 
+            Drain (Pull-up, Pull-down or no Pull).
+       (++) Analog: required mode when a pin is to be used as ADC channel or DAC 
+            output.
+   
+   (#) Peripherals alternate function:
+       (++) For ADC and DAC, configure the desired pin in analog mode using 
+            GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN;
+            (+++) For other peripherals (TIM, USART...):
+            (+++) Connect the pin to the desired peripherals' Alternate 
+                     Function (AF) using GPIO_PinAFConfig() function
+            (+++) Configure the desired pin in alternate function mode using
+                     GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
+            (+++) Select the type, pull-up/pull-down and output speed via 
+                     GPIO_PuPd, GPIO_OType and GPIO_Speed members
+            (+++) Call GPIO_Init() function
+          
+   (#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
+            
+   (#) To set/reset the level of a pin configured in output mode use 
+       GPIO_SetBits()/GPIO_ResetBits()
+                 
+   (#) During and just after reset, the alternate functions are not 
+       active and the GPIO pins are configured in input floating mode (except JTAG
+       pins).
+  
+   (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose 
+       (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has 
+       priority over the GPIO function.

+   (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as 
+       general purpose PH0 and PH1, respectively, when the HSE oscillator is off. 
+       The HSE has priority over the GPIO function.

+ *** HASH operation : *** 
+ ========================                 
+ [..]
+   (#) Enable the HASH controller clock using 
+       RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_HASH, ENABLE) function.
+             
+   (#) Initialise the HASH using HASH_Init() function. 
+                 
+   (#) Reset the HASH processor core, so that the HASH will be ready 
+       to compute he message digest of a new message by using HASH_Reset() function.
+  
+   (#) Enable the HASH controller using the HASH_Cmd() function. 
+                  
+   (#) if using DMA for Data input transfer, Activate the DMA Request 
+       using HASH_DMACmd() function 
+                      
+   (#) if DMA is not used for data transfer, use HASH_DataIn() function 
+       to enter data to IN FIFO.
+               
+            
+   (#) Configure the Number of valid bits in last word of the message 
+       using HASH_SetLastWordValidBitsNbr() function.
+               
+   (#) if the message length is not an exact multiple of 512 bits, 
+       then the function HASH_StartDigest() must be called to launch the computation
+       of the final digest.     
+               
+   (#) Once computed, the digest can be read using HASH_GetDigest() function.         
+                     
+   (#) To control HASH events you can use one of the following wo methods:
+       (++) Check on HASH flags using the HASH_GetFlagStatus() function.  
+       (++) Use HASH interrupts through the function HASH_ITConfig() at 
+            initialization phase and HASH_GetITStatus() function into 
+            interrupt routines in hashing phase.
+            After checking on a flag you should clear it using HASH_ClearFlag()
+            function. And after checking on an interrupt event you should 
+            clear it using HASH_ClearITPendingBit() function.     
+                       
+   (#) Save and restore hash processor context using 
+       HASH_SaveContext() and HASH_RestoreContext() functions.     
+                
+  
+              
+ *** HMAC operation : *** 
+ ========================
+ [..] The HMAC algorithm is used for message authentication, by 
+      irreversibly binding the message being processed to a key chosen 
+      by the user. 
+      For HMAC specifications, refer to "HMAC: keyed-hashing for message 
+      authentication, H. Krawczyk, M. Bellare, R. Canetti, February 1997"
+            
+ [..] Basically, the HMAC algorithm consists of two nested hash operations:
+      HMAC(message) = Hash[((key | pad) XOR 0x5C) | Hash(((key | pad) XOR 0x36) | message)]
+      where:
+      (+) "pad" is a sequence of zeroes needed to extend the key to the 
+          length of the underlying hash function data block (that is 
+          512 bits for both the SHA-1 and MD5 hash algorithms)
+      (+) "|"   represents the concatenation operator 
+            
+           
+ [..]To compute the HMAC, four different phases are required:                  
+   (#) Initialise the HASH using HASH_Init() function to do HMAC 
+       operation. 
+                  
+   (#) The key (to be used for the inner hash function) is then given to the core. 
+       This operation follows the same mechanism as the one used to send the 
+       message in the hash operation (that is, by HASH_DataIn() function and, 
+       finally, HASH_StartDigest() function.
+            
+   (#) Once the last word has been entered and computation has started, 
+       the hash processor elaborates the key. It is then ready to accept the message
+       text using the same mechanism as the one used to send the message in the
+       hash operation.
+         
+   (#) After the first hash round, the hash processor returns "ready" to indicate 
+       that it is ready to receive the key to be used for the outer hash function 
+       (normally, this key is the same as the one used for the inner hash function). 
+       When the last word of the key is entered and computation starts, the HMAC 
+       result is made available using HASH_GetDigest() function.

+ *** Interrupts : ***
+ ====================

+       locations are free in the Data IN FIFO  which means that a new block (512 bit)

+  * @brief   This file provides firmware functions to manage the following 
+  *          functionalities of the Independent watchdog (IWDG) peripheral:           
+  *           + Prescaler and Counter configuration

+  *           + Flag management

+    @verbatim    
+ ===============================================================================
+                          ##### IWDG features #####
+ ===============================================================================
+    [..]  
+      The IWDG can be started by either software or hardware (configurable
+      through option byte).
+              
+      The IWDG is clocked by its own dedicated low-speed clock (LSI) and
+      thus stays active even if the main clock fails.
+      Once the IWDG is started, the LSI is forced ON and cannot be disabled
+      (LSI cannot be disabled too), and the counter starts counting down from 
+      the reset value of 0xFFF. When it reaches the end of count value (0x000)
+      a system reset is generated.
+      The IWDG counter should be reloaded at regular intervals to prevent
+      an MCU reset.
+                             
+      The IWDG is implemented in the VDD voltage domain that is still functional
+      in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).          
+              
+      IWDGRST flag in RCC_CSR register can be used to inform when a IWDG
+      reset occurs.
+              
+      Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
+      The IWDG timeout may vary due to LSI frequency dispersion. STM32F4xx
+      devices provide the capability to measure the LSI frequency (LSI clock
+      connected internally to TIM5 CH4 input capture). The measured value
+      can be used to have an IWDG timeout with an acceptable accuracy. 
+      For more information, please refer to the STM32F4xx Reference manual
+            
+                     ##### How to use this driver #####
+ ===============================================================================
+    [..]
+      (#) Enable write access to IWDG_PR and IWDG_RLR registers using
+          IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function
+                 
+      (#) Configure the IWDG prescaler using IWDG_SetPrescaler() function
+              
+      (#) Configure the IWDG counter value using IWDG_SetReload() function.
+          This value will be loaded in the IWDG counter each time the counter
+          is reloaded, then the IWDG will start counting down from this value.
+              
+      (#) Start the IWDG using IWDG_Enable() function, when the IWDG is used
+          in software mode (no need to enable the LSI, it will be enabled
+          by hardware)
+               
+      (#) Then the application program must reload the IWDG counter at regular
+          intervals during normal operation to prevent an MCU reset, using
+          IWDG_ReloadCounter() function.

+      (+) The backup domain includes 4 Kbytes of backup SRAM accessible only from

+          save battery life.
+
+      (+) The backup SRAM is not mass erased by an tamper event. It is read 
+          protected to prevent confidential data, such as cryptographic private

+      (+) For STM32F405xx/407xx and STM32F415xx/417xx  Devices, the regulator can be     
+          configured on the fly through PWR_MainRegulatorModeConfig() function which

+             the System frequency can go up to 168 MHz. 
+        (++) When this bit is reset (Regulator voltage output Scale 2 mode selected) 
+             the System frequency can go up to 144 MHz.
+             
+       (+) For STM32F42xxx/43xxx Devices, the regulator can be configured through    
+           PWR_MainRegulatorModeConfig() function which configure VOS[1:0] bits in
+           PWR_CR register:  
+           which configure VOS[1:0] bits in PWR_CR register: 
+        (++) When VOS[1:0] = 11 (Regulator voltage output Scale 1 mode selected) 
+             the System frequency can go up to 168 MHz. 
+        (++) When VOS[1:0] = 10 (Regulator voltage output Scale 2 mode selected) 
+             the System frequency can go up to 144 MHz.

+                          
+       (+) For STM32F42xxx/43xxx Devices, the scale can be modified only when the PLL 
+           is OFF and the HSI or HSE clock source is selected as system clock. 
+           The new value programmed is active only when the PLL is ON.
+           When the PLL is OFF, the voltage scale 3 is automatically selected. 
+        Refer to the datasheets for more details.
+        
+       (+) For STM32F42xxx/43xxx Devices, in Run mode: the main regulator has
+           2 operating modes available:
+        (++) Normal mode: The CPU and core logic operate at maximum frequency at a given 
+             voltage scaling (scale 1, scale 2 or scale 3)
+        (++) Over-drive mode: This mode allows the CPU and the core logic to operate at a 
+            higher frequency than the normal mode for a given voltage scaling (scale 1,  
+            scale 2 or scale 3). This mode is enabled through PWR_OverDriveCmd() function and

+            the sequence described in Reference manual.
+             
+       (+) For STM32F42xxx/43xxx Devices, in Stop mode: the main regulator or low power regulator 
+           supplies a low power voltage to the 1.2V domain, thus preserving the content of registers 
+           and internal SRAM. 2 operating modes are available:
+         (++) Normal mode: the 1.2V domain is preserved in nominal leakage mode. This mode is only 
+              available when the main regulator or the low power regulator is used in Scale 3 or 
+              low voltage mode.
+         (++) Under-drive mode: the 1.2V domain is preserved in reduced leakage mode. This mode is only
+              available when the main regulator or the low power regulator is in low voltage mode.
+              This mode is enabled through PWR_UnderDriveCmd() function.

+      The devices feature 3 low-power modes:
+      (+) Sleep mode: Cortex-M4 core stopped, peripherals kept running.
+      (+) Stop mode: all clocks are stopped, regulator running, regulator 
+          in low power mode
+      (+) Standby mode: 1.2V domain powered off.
+   
+   *** Sleep mode ***
+   ==================
+    [..]
+      (+) Entry:
+        (++) The Sleep mode is entered by using the __WFI() or __WFE() functions.
+      (+) Exit:
+        (++) Any peripheral interrupt acknowledged by the nested vectored interrupt 
+             controller (NVIC) can wake up the device from Sleep mode.
+
+   *** Stop mode ***
+   =================
+    [..]
+      In Stop mode, all clocks in the 1.2V domain are stopped, the PLL, the HSI,
+      and the HSE RC oscillators are disabled. Internal SRAM and register contents 
+      are preserved.
+      The voltage regulator can be configured either in normal or low-power mode.
+      To minimize the consumption In Stop mode, FLASH can be powered off before

+      The 1.2V domain is consequently powered off. The PLL, the HSI oscillator and 
+      the HSE oscillator are also switched off. SRAM and register contents are lost 
+      except for the RTC registers, RTC backup registers, backup SRAM and Standby 
+      circuitry.
