STC单片机PCA捕获中断函数

**函数名称：void PCA_Capture_Int();**功能描述：PCA捕获中断函数，扩展32位计数**说    明：中断发生后，计数器将32计数结果高位写入/***************************************************/void PCA_Capture_Int(){//PCA捕获中断if(CR){//如果计数器溢出PCA_0.Dou_L++;                 //模块0高位临时变量自加PCA_1.Dou_L++;                 //模块1高位临时变量自加}if(CCF0){//如果模块0引脚接受中断CCF0 = 0;                      //清中断PCA_0.Match = CCAP0H;PCA_0.Match <= 8;PCA_0.Match &= CCAP0L;         //低位保存PCA_0.Dou_H = PCA_0.Dou_L;     //高位保存PCA_0.Dou_L = 0;              //清空高位自加容器}if(CCF1){//如果模块1引脚接受中断CCF1 = 0;                     //清中断PCA_1.Match = CCAP1H;PCA_1.Match <= 8;PCA_1.Match &= CCAP1L;        //低位保存PCA_1.Dou_H = PCA_1.Dou_L;    //高位保存PCA_1.Dou_L = 0;              //清空高位自加容器}}
