• Remapping the memory mapped at 0x00000000
• Remapping the DMA channels
• Enabling I2C fast mode plus driving capability for I2C plus
• Remapping USB interrupt line
• Configuring the EXTI lines connection to the GPIO port
• Configuring the CLASSB requirements

===============================================================================
                     ##### How to use this driver #####
===============================================================================
   [..] The SYSCFG registers can be accessed only when the SYSCFG 
        interface APB clock is enabled.
   [..] To enable SYSCFG APB clock use:
        RCC_APBPeriphClockCmd(RCC_APBPeriph_SYSCFG, ENABLE);
