F28035 ADCINT1触发CLA任务1问题

1、为什么我在实验时候，F28035 用ADCINT1触发CLA任务，配置了ADC和PWM，最后配置CLA，任务运行不了自动进入下面这个默认中断

__interrupt void rsvd_ISR(void) // For test
{
__asm (" ESTOP0");
for(;;);
}

2、不用ADC触发，软件触发CLA，都能正常运行；但是在配置最后，屏蔽了CLA的任务完成中断，也会运行不了CLA任务，如下。

// PieCtrlRegs.PIEIER11.all = 0xFFFF;
// IER = (M_INT11 );

3、将 IER = (M_INT11 ); 改为IER |= (M_INT11); 也会运行不了CLA任务。

ADC转换完成，触发CLA任务，该怎么配置ADC呢？必须在ADC中断函数里面清除ADC中断标志吗,我都试过，都运行不了
我是这样的：
__interrupt void ADC_CLAISR(void)
{
EALLOW;
PieCtrlRegs.PIEACK.bit.ACK10 = 1; // Acknowledge interrupt to PIE
EDIS;
AdcRegs.ADCINTFLGCLR.bit.ADCINT1 = 1;//Clear ADCINT1 flag reinitialize for next SOC
}

void ADC_CONFIG_SET(void)
{
ChSel[0] = 4;
ChSel[1] = 4;
ChSel[2] = 1;
ChSel[3] = 3;
ChSel[4] = 7;
ChSel[5] = 6;
ChSel[6] = 2;

TrigSel[0] = ADCTRIG_EPWM1_SOCA;
TrigSel[1] = ADCTRIG_EPWM1_SOCA;
TrigSel[2] = ADCTRIG_EPWM1_SOCA;
TrigSel[3] = ADCTRIG_EPWM1_SOCA;
TrigSel[4] = ADCTRIG_EPWM1_SOCA;
TrigSel[5] = ADCTRIG_EPWM1_SOCA;
TrigSel[6] = ADCTRIG_EPWM1_SOCA;

EPwm1Regs.ETSEL.bit.SOCAEN = 1;
EPwm1Regs.ETSEL.bit.SOCASEL = ET_CTR_ZERO;
EPwm1Regs.ETPS.bit.SOCAPRD = ET_1ST;

}

可以参考例程的配置
