 ===============================================================================
                     ##### 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().
         (#) Routing of I/Os toward the input captures of timers (TIM2, TIM3 and TIM4).
         (#) Input routing of COMP1 and COMP2.
         (#) Routing of internal reference voltage VREFINT to PB0 and PB1.
         (#) The RI registers can be accessed only when the comparator
             APB interface clock is enabled.
             To enable comparator clock use:
             RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
             Following functions uses RI registers:
             (++) SYSCFG_RIDeInit()
             (++) SYSCFG_RITIMSelect()
             (++) SYSCFG_RITIMInputCaptureConfig()
             (++) SYSCFG_RIResistorConfig()
             (++) SYSCFG_RIChannelSpeedConfig()
             (++) SYSCFG_RIIOSwitchConfig()
             (++) SYSCFG_RISwitchControlModeCmd()
             (++) SYSCFG_RIHysteresisConfig()
         (#) The SYSCFG registers can be accessed only when the SYSCFG
             interface APB clock is enabled.
             To enable SYSCFG APB clock use:
             RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
             Following functions uses SYSCFG registers:
             (++) SYSCFG_DeInit()  
             (++) SYSCFG_MemoryRemapConfig()
             (++) SYSCFG_GetBootMode()  
             (++) SYSCFG_USBPuCmd()
             (++) SYSCFG_EXTILineConfig()
