哪个帮我看下这两句话必须要
interrupt void SCIRXINTA_ISR_m(void) // SCI-B{ static unsigned int RxBuf;PieCtrlRegs.PIEACK.bit.ACK9 = 1; 必须要不 RxBuf=SciaRegs.SCIRXBUF.all;CHUAN=CHUAN+10;switch(RxBuf){case 0://增加输入电压百分比 P=P+0.1; break;case 1://运行 P=P-0.1; break;}EINT; 必须要不 }

Answer 1

PieCtrlRegs.PIEACK.bit.ACK9 = 1,对应答标志写1清0,即允许INT9向CPU申请中断；EINT：全局使能必须要不 查看原帖>>
