CAN 接收中断中吧不用清除中断标志位吗？

尼泊尔123

我配置的时候是 
/*CAN 通信中断使能*/
33 CAN_ITConfig(CAN1, CAN_IT_FMP0, ENABLE);
但是中断标志位清除函数 确没有 CAN_IT_FMP0  这个参数，只有满和溢出，难道是硬件自动清除的吗？

void CAN_ClearITPendingBit	(	CAN_TypeDef *	CANx,
		uint32_t	CAN_IT
	)

Clears the CANx's interrupt pending bits.

Parameters:

CANx,:	where x can be 1 or 2 to to select the CAN peripheral.
CAN_IT,:	specifies the interrupt pending bit to clear. CAN_IT_TME CAN_IT_FF0 CAN_IT_FOV0 CAN_IT_FF1 CAN_IT_FOV1 CAN_IT_WKU CAN_IT_SLK CAN_IT_EWG CAN_IT_EPV CAN_IT_BOF CAN_IT_LEC CAN_IT_ERR

CAN_ITConfig(CAN1,CAN_IT_FMP0,ENABLE);
只需要读取CAN_Receive(CAN1, 0, &RxMessage);就行  无需要清中断
