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