ADC for MCBSTR9

Hello Keil users,

I'm trying to display a ADC value on eval board.
( I already post a similar thread but this time is not the same).

The problem is that ADC displayed on board varies between 0 and 10. And I want it to vary between 0 and 1024.

Any idea ?

short AD_value = 0x00
void ADC_IRQ_Handler(void)
{
        ADC->CR &= 0xFFFE;                       /* Clear STR bit (Start Conversion)   */
        ADC->CR &= 0x7FFF;                       /* Clear End of Conversion flag       */

        VIC0->VAR = 0;                               /* Acknowledge Interrupt              */
        VIC1->VAR = 0;

        AD_value = ADC->DR0 & 0x03FF;            /* AD value for global usage (10 bit) */
        ADConversation = TRUE;                  /* Signal, that AD-conversion has finished */
}

And the called function is

ADConversation = FALSE;
                                ADC->CR |= 0x0403;                  /* Set STR bit (Start Conversion) */
                                while(!ADConversation) {}               /* Wait until AD-conversation has finished */

                                lcd_init();
                                lcd_clear();
                                set_cursor(0,0);
                                sprintf(text1,"Analog Value %5d",AD_value);
                                lcd_print(text1);

ADConversation is a bool.

Thanks in advance.
