中断函数, dc, AD, ADC1, ADC

#include
static unsigned int results;
void main(void)
{
  volatile unsigned int i;//unsigned long int j;
  WDTCTL = WDTPW+WDTHOLD;                // Stop watchdog timer
  P6SEL |= 0x01;                         // Enable A/D channel A0
  ADC12CTL0 = ADC12ON+SHT0_2+REFON+REF2_5V; // Turn on and set up ADC12
  ADC12CTL1 = SHP+CONSEQ_0;                         // Use sampling timer
  ADC12MCTL0 = SREF_1;                   // Vr+=Vref+
  P4DIR=0X01; ADC12IE = 0x01;
  for ( i=0; i<0x3600; i++)                // Delay for reference start-up
  {
  }
  _EINT();
  ADC12CTL0 |= ENC;                      // Enable conversions
while (1)
{
ADC12CTL0 |= ADC12SC;
}
}

#pragma vector=ADC_VECTOR
__interrupt void ADC12ISR (void)
{
  results = ADC12MEM0;
  if(results<=0x7ff)
   P4OUT=0X01;
  else  P4OUT=0X00;
  //_BIC_SR_IRQ(LPM0_bits);                // Clear LPM0, SET BREAKPOINT HERE
