// Select the channel's trigger source        选择触发源

         AdcRegs.ADCSOC0CTL.bit.TRIGSEL = 0x00;      //set SOC0 start trigger on software only 选择软件触发SOC

         AdcRegs.ADCSOC1CTL.bit.TRIGSEL = 0x00;

         AdcRegs.ADCSOC3CTL.bit.TRIGSEL = 0x00;

         AdcRegs.ADCSOC7CTL.bit.TRIGSEL = 0x00;

         AdcRegs.ADCSOC9CTL.bit.TRIGSEL = 0x00;

         AdcRegs.ADCSOC11CTL.bit.TRIGSEL = 0x00;

         AdcRegs.ADCSOC15CTL.bit.TRIGSEL= 0x00;

什么是软件触发，它与ePWM1中产生的ADCSOCA触发AD转换有什么不同？？？？？
