MSP430F169: ADC was not working

Hi,

I wrote a c code for accessing the internal ADC of MSP430F169.

Here is my code.

void main(void)
{

unsigned int adc_count;

WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer

DCOCTL = DCO0 + DCO1 + DCO2;

BCSCTL1 = XT2OFF + DIVA_3 + RSEL0 + RSEL1 + RSEL2;

BCSCTL2 = SELM_0 + DIVM_1 + DIVS_1;

P2DIR |= 0x01; // configure P1.0 as output

P6SEL |= 0x01;

ADC12CTL0 = ADC12ON + REF2_5V + REFON;

ADC12CTL1 = ADC12SSEL_0 + ADC12DIV_3;

ADC12MCTL0 = 0x90;

ADC12CTL0 |= ENC;

while(1)

{

ADC12CTL0 |= ADC12SC;

while(!(ADC12IFG & 0x0001));

ADC12MEM0;

P2OUT ^= 0x01;

}

}

But I didin't getting the ADC A0 interrupt flag so the execution was stopping at while loop.

Is my configuration correct ?

Thanks

Regards
