21.2 SYSCFG Firmware driver API description
The following section lists the various functions of the SYSCFG library.
21.2.1 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);
