  • Remapping the memory mapped at 0x00000000
  • Remapping the DMA channels
  • Enabling I2C fast mode plus driving capability for I2C pins
  • Configuring the EXTI lines connection to the GPIO port
  • Configuring the CFGR2 features (Connecting some internal signal to the break input of TIM1)

   [..] 
              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).
