TI中文支持网我用EPWM6_SOCA 触发 TMS320F280049 的三个ADC模块 ，每个ADC模块有4个SOC ,
EPWM6_SOCA 触发 adca 的 SOC0 ~ SOC3 ,用SOC3触发 INT_ADCA1 中断。
EPWM6_SOCA 触发 adcb 的 SOC0 ~ SOC3 ,用SOC3触发 INT_ADCB1 中断。
EPWM6_SOCA 触发 adcc 的 SOC0 ~ SOC3 ,用SOC3触发 INT_ADCC1 中断。
刚运行时，三个中断都可以正常进入。运行了一段时间后，有的中断就不能进入，或者三个中断都不能进入。有可能是什么原因？
代码如下。
#define TRIGGER_SOURCE_3 ADC_TRIGGER_EPWM6_SOCA //触发源
三个ADC模块的配置
//adca
ADC_setVREF(ADCA_BASE, ADC_REFERENCE_MODE, ADC_REFERENCE_VOLT);

三个中断函数。
__interrupt void adcaInterrupt_1(void)
{
ADC_clearInterruptStatus(ADCA_BASE, ADC_INT_NUMBER1);
Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP1);
}
__interrupt void adcbInterrupt_1(void)
{
ADC_clearInterruptStatus(ADCB_BASE, ADC_INT_NUMBER1);
Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP1);
}
__interrupt void adccInterrupt_1(void)
{
ADC_clearInterruptStatus(ADCC_BASE, ADC_INT_NUMBER1);
Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP1);
}

仿真时：
中断标志：ADCINTFLAG.ACINT1 已经置位
中断使能：ADCINTSEL1N2.INT1SEL 已经置位
同时，中断溢出标志ADCINTOVF.ACINT1 也置位
就是进不了中断
