MSP430F5510: ADC10 interrupt not triggering

Part Number: MSP430F5510

Hello,

I am having trouble getting the ADC10 interrupt for the msp430f5510 to trigger. Once I call the function lectura_ADC, to read a value from channel 0, the CPU doesn't "wake up" since the interrupt doesn't get triggered, and consequently I can't get a safe value from the ADC.

Code below...

#include <stdint.h>
#include <msp430.h>
#include <stdlib.h>
#include <Timer.h>


void init_adc10(void)
{
P6SEL |= BIT0 | BIT1;
ADC10CTL0 = ADC10SHT_12 | ADC10ON | ADC10IE | ADC10SREF0 | ADC10SC;

ADC10CTL1 |= ADC10SSEL_0 + ADC10SHP;

ADC10CTL2 |= ADC10RES;

}

unsigned int lectura_ADC(int canal){

unsigned int conv = 0;
ADC10CTL0 &= ~ADC10ENC;
ADC10MCTL0 = ADC10INCH0;
delay_ms(10);
ADC10CTL0 |= ADC10ENC | ADC10SC ;

__bis_SR_register(CPUOFF + GIE);
conv = ADC10MEM0;
delay_ms(10);
return conv;

}

#pragma vector = ADC10_VECTOR
__interrupt void ADC10_ISR(void)
{

__bic_SR_register_on_exit(CPUOFF);


}
