STC單片機PCA捕獲中斷函數(shù)

**函數(shù)名稱：void PCA_Capture_Int();**功能描述：PCA捕獲中斷函數(shù)，擴展32位計數(shù)**說    明：中斷發(fā)生后，計數(shù)器將32計數(shù)結(jié)果高位寫入/***************************************************/void PCA_Capture_Int(){//PCA捕獲中斷if(CR){//如果計數(shù)器溢出PCA_0.Dou_L++;                 //模塊0高位臨時變量自加PCA_1.Dou_L++;                 //模塊1高位臨時變量自加}if(CCF0){//如果模塊0引腳接受中斷CCF0 = 0;                      //清中斷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){//如果模塊1引腳接受中斷CCF1 = 0;                     //清中斷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}}
