以上为初始化部分
下面为ADC单次采集，获取结果后再次启动采集，已获取多次结果累积。
以下函数上电后，有获取一次或数次结果，就无法再进入了。
void module_adc (void)
{
if (ADC_GET_INT_FLAG(ADC,ADC_ADF_INT))
{
ADC_CLR_INT_FLAG(ADC,ADC_ADF_INT);
glv_temp1 = ADC_GET_CONVERSION_DATA(ADC,0);
ADC_START_CONV(ADC);
}
}
函数入口判定试了，ADC_GET_INT_FLAG，ADC_IS_BUSY，ADC_IS_DATA_OVERRUN，ADC_IS_DATA_VALID都是进入一次或数次，然后就不再进入了。
找了一整天的问题，都没找出原因，请老师们帮帮忙，谢谢。
