I'm using EVAL - ADUC7061MKZ and IAR Embedded Workbench. I've statred ADC and trying to get ADC result via interrupt system, but my program doesn't enter in IRQ_HANDLER. Source samples here:

}
int main(void)
{
init(); init_acp(); IRQEN = BIT10; // Enable Timer 0 IRQ while (1) { longtodisp(Ves); disp_out(); delay(delay_ms); }
}
__irq void IRQ_Handler(void)
{
unsigned long IRQSTATUS = 0; IRQSTATUS = IRQSTA; // Read off IRQSTA register Ves = 1000; if ((IRQSTATUS & BIT10) == BIT10) //If ADC0 interrupt source { Ves = ADC0DAT; }
}
What wrong?
