MSP430G2553,TSSOP20封装的，支持ADC10吗。都没有看到AVCC的供电啊

可以使用ADC的，这是一个官方例程

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                                         // Stop WDT
  ADC10CTL0 = ADC10SHT_2 + ADC10ON + ADC10IE;    // ADC10ON, interrupt enabled
  ADC10CTL1 = INCH_1;                       // input A1
  ADC10AE0 |= 0x02;                         // PA.1 ADC option select
  P1DIR |= 0x01;                            // Set P1.0 to output direction

  for (;;)
  {
    ADC10CTL0 |= ENC + ADC10SC;             // Sampling and conversion start
    __bis_SR_register(CPUOFF + GIE);        // LPM0, ADC10_ISR will force exit
    if (ADC10MEM < 0x1FF)
      P1OUT &= ~0x01;                       // Clear P1.0 LED off
    else
      P1OUT |= 0x01;                        // Set P1.0 LED on
  }
}

// ADC10 interrupt service routine
#pragma vector=ADC10_VECTOR
__interrupt void ADC10_ISR(void)
{
  __bic_SR_register_on_exit(CPUOFF);        // Clear CPUOFF bit from 0(SR)
}

谢谢，看了手册上面的框图，上面供电都是AVCC的   TSSOP20的封装只有DVCC   所以想知道内部是怎么处理的，手册上没有介绍
