Detailed Description

This file provides firmware functions to manage the following functionalities of the SYSCFG peripheral:

MCD Application Team
  • 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);
