*                                 How to use this driver
*          ===================================================================
*                  
*          This driver provides functions for:
*          
*          1. Remapping the memory accessible in the code area using SYSCFG_MemoryRemapConfig()
*              
*          2. Manage the EXTI lines connection to the GPIOs using SYSCFG_EXTILineConfig()
*            
*          3. Select the ETHERNET media interface (RMII/RII) using SYSCFG_ETH_MediaInterfaceConfig()
*
*  @note  SYSCFG APB clock must be enabled to get write access to SYSCFG registers,
*         using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
*                 
*
