28027例程中adc初始化中AdcRegs.ADCSOCFRC1置位意义？-TI中文支持网

如题，在controlSUITE\development_kits\HVPSFB_v1.1\HVPSFB_PCMC 中ADC_SOC_CNF（）函数最后对AdcRegs.ADCSOCFRC1.all置位，该置位会导致adc转换一直进行吗？该寄存器的置位是否能自动清零？我在adc的参考指南中并没有看到更详细的说明，希望能得到官方的解释，谢谢？

代码及寄存器说明如下：

Eric Ma：

这个位是软件产生一次强制ADC转换。

代码及寄存器说明如下：

void ADC_SOC_CNF(int ChSel[], int Trigsel[], int ACQPS[], int IntChSel, int mode)
{

extern void DSP28x_usDelay(Uint32 Count);

DSP28x_usDelay(1000); // Delay before converting ADC channels

AdcRegs.ADCCTL1.bit.INTPULSEPOS = 1;//脉冲产生在写结果之后何德威2016.12.5

AdcRegs.INTSEL1N2.bit.INT1SEL = IntChSel; // IntChSel causes ADCInterrupt 1

   if(IntChSel<15)
       AdcRegs.INTSEL1N2.bit.INT1E = 1;       // enable ADC interrupt 1
   else
       AdcRegs.INTSEL1N2.bit.INT1E = 0;       // disable the ADC interrupt 1

AdcRegs.ADCSOCFRC1.all = 0xFFFF; // kick-start ADC

也就是对这个寄存器软件写1只能执行一次adc转换就停下来是吧，那么执行一次转换后，该寄存器的值是否会变为0呢，我手头现在没有板子没办法做实验

代码及寄存器说明如下：

void ADC_SOC_CNF(int ChSel[], int Trigsel[], int ACQPS[], int IntChSel, int mode)
{

extern void DSP28x_usDelay(Uint32 Count);

DSP28x_usDelay(1000); // Delay before converting ADC channels

AdcRegs.ADCCTL1.bit.INTPULSEPOS = 1;//脉冲产生在写结果之后何德威2016.12.5

AdcRegs.INTSEL1N2.bit.INT1SEL = IntChSel; // IntChSel causes ADCInterrupt 1

   if(IntChSel<15)
       AdcRegs.INTSEL1N2.bit.INT1E = 1;       // enable ADC interrupt 1
   else
       AdcRegs.INTSEL1N2.bit.INT1E = 0;       // disable the ADC interrupt 1

AdcRegs.ADCSOCFRC1.all = 0xFFFF; // kick-start ADC

}

回复 dewei he:

会清零。
