KEA128进不了AD中断问题

哪位大虾帮我看看，我为什么进不了AD采样完成中断，是哪个寄存器没写对还是中断函数没写对，急急急！！！谢谢。
void init_ADC(void)  {
  SIM_SCGC |= SIM_SCGC_ADC_MASK; /* Enable bus clock to ADC module */
  ADC_SC1 = 0x4A;
                                                                     /* AIEN = 1: Interrupts enabled  */
                                                                  /* ADCO = 1: Continuous conversions enabled  */

  ADC_APCTL1 = 0x00000400;             /* Enable ADC channels 10 (PTC2) */
  ADC_SC3 = 0x00000005;                /* Select ADCACLK, no divide, 10 bit conversion */
                                    /* ADLPC = 0 (default): hi speed config */
                                    /* ADIV = 0 (default): clock rate = input clock/1 */
                                    /* ADLSMP = 0 (default): short sample time */
                                    /* MODE = 1: 10 bit conversion */
                                    /* ADICLK= 1:Bus clock/2 source */
  ADC_SC2 =0x00000000;                /* SW trigger, default ref pins, no compare */
                                                      /* ADTRG = 0 (default): SW Trigger */
                                    /* ACFE = 0 (default):  compare function disabled */
                                                      /* REFSEL = 0 (default): default ref volt pin pair */
}

中断向量表：
/* The Interrupt Vector Table */
void (* const InterruptVector[])() __attribute__ ((section(".vectortable"))) = {
/* Processor exceptions */
(void(*)(void)) &_estack,
__thumb_startup,
NMI_Handler,
HardFault_Handler,
         .
         .
         .
ADC0_IRQHandler, /* ADC conversion complete interrupt */
         .
         .
         .
};

void ADC0_IRQHandler() __attribute__ ((weak, alias("Default_Handler")));

main(void)
{
   init_clks_FEE_40MHz();
   init_ADC();
   Enable_Interrupt(INT_ADC0);    /* Enable ADC0 interrupt */


for(;;) {
   a ++;
}
}

void ADC0_IRQHandler(void){    //中断函数
counter++;
}
