STM32H743 IO口中断配置

      我需要配置PC5的中断及使能，在STM32F103中的配置如下，在h743中需要如何配置呢？只找到HAL_NVIC_SetPriority();
  HAL_NVIC_EnableIRQ(）;这两函数

STM32F103中的配置如下：

// 配置外部中断
void EXTI_Config(void)
{
EXTI_InitTypeDef  EXTI_InitStructure ;

GPIO_EXTILineConfig(GPIO_PortSourceGPIOC, GPIO_PinSource5);//管脚选择
EXTI_ClearITPendingBit(EXTI_Line5);    //清除中断标志

EXTI_InitStructure.EXTI_Line = EXTI_Line5;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;    //下降沿触发采样
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);
}

void NVIC_Config(void)
{
NVIC_InitTypeDef  NVIC_InitStructure ;

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);
NVIC_InitStructure.NVIC_IRQChannel = EXTI9_5_IRQChannel;       //5~9通道
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;//占先级
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;                      //响应级
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;                      //启动
    NVIC_Init(&NVIC_InitStructure);                                     //初始化
}
