+  *            toolchain.
+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address
+  *                - Configure the clock system                 
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M3 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.

+  *       sends a stop condition and data transmission is stopped.
+  *    
+  * - Slave Transmitter mode:
+  *    - EV3: When a byte has been transmitted by the slave and the application is expecting 
+  *      the end of the byte transmission. The two events I2C_EVENT_SLAVE_BYTE_TRANSMITTED and
+  *      I2C_EVENT_SLAVE_BYTE_TRANSMITTING are similar. The second one can optionally be 
+  *      used when the user software doesn't guarantee the EV3 is managed before the
+  *      current byte end of transfer.
+  *    - EV3_2: When the master sends a NACK in order to tell slave that data transmission 
+  *      shall end (before sending the STOP condition). In this case slave has to stop sending 
+  *      data bytes and expect a Stop condition on the bus.
+  *      
+  *  @note In case the  user software does not guarantee that the event EV2 is

+ ****************************************************************************************
+ *
+ *                         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 
+ *      (RM0008).
+ *      - 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 I2Cx_ER_IRQHandler()
+ *            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() 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 limitations of I2C_GetFlagStatus() function (see below).
+ *         The returned value could be compared to events already defined in the 
+ *         library (stm32f10x_i2c.h) 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() 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.
+ *
