AdcRegs.INTSEL1N2.bit.INT1SEL寄存器设置是7一切正常，设为8，ADC没有中断是为什么

AdcRegs.INTSEL1N2.bit.INT1SEL = 8; //setup EOC5 to trigger ADCINT1 to fire,SOC5转换完成产生中断

    TMS320F2803x 我想知道为什么会发生这种情况，还有如果设置SOC8,应该怎么修改，谢谢

    尝试一下把上述程序

    AdcRegs.ADCSOC0CTL.bit.CHSEL = 7; //SOC0 ADCINA1 //ADCINA7

    AdcRegs.ADCSOC1CTL.bit.CHSEL = 8; //SOC0 ADCINA1 //ADCINB0
    AdcRegs.ADCSOC2CTL.bit.CHSEL = 9; //SOC0 ADCINA1 //ADCINB1
    AdcRegs.ADCSOC3CTL.bit.CHSEL = 10; //SOC0 ADCINA1 //ADCINB2

    AdcRegs.ADCSOC5CTL.bit.CHSEL = 12; //SOC0 ADCINA1 //ADCINB4
    AdcRegs.ADCSOC6CTL.bit.CHSEL = 14; //SOC0 ADCINA1 //ADCINB6
    AdcRegs.ADCSOC7CTL.bit.CHSEL = 15; //SOC0 ADCINA1 //ADCINB7

    AdcRegs.ADCSOC8CTL.bit.CHSEL = 6; //ADCINA6

    替换成

    AdcRegs.ADCSOC0CTL.bit.CHSEL = 7; 

AdcRegs.ADCSOC1CTL.bit.CHSEL = 7; 
AdcRegs.ADCSOC2CTL.bit.CHSEL = 8; 
AdcRegs.ADCSOC3CTL.bit.CHSEL = 9; 
AdcRegs.ADCSOC4CTL.bit.CHSEL = 10; 
AdcRegs.ADCSOC5CTL.bit.CHSEL = 11; 
AdcRegs.ADCSOC6CTL.bit.CHSEL = 12; 
AdcRegs.ADCSOC7CTL.bit.CHSEL = 14; 

AdcRegs.ADCSOC8CTL.bit.CHSEL = 15;

    测试一下是否有效。其他问题暂时没看出来

    如果方便的话可以把工程转压缩文件后上传一下
