TMS320F280039: 80pin的280039芯片中TZ中断配置问题

Part Number: TMS320F280039
我现在有这样一个问题需要你帮我解决一下，我在280039芯片上用六个PWM配置成控制两个电机，其中PWM7,PWM1,PWM5控制电机1，PWM2,PWM4,PWM3控制电机2，我现在需要给电机1和电机2分别配置两个TZ中断来做过流保护，配置一个TZ中断做过压保护，所以我把控制电机1的PWM7,PWM1,PWM5配置TZ1中断用来做过流保护,把控制电机2的PWM7,PWM1,PWM5配置TZ2中断用来做过流保护,最后把控制电机1的PWM7,PWM1,PWM5和,把控制电机2的PWM7,PWM1,PWM5配置TZ3中断用来做过压保护，但是我现在的问题是，无论哪个tz事件发送，都会触发三个中断，好像三个中断被绑在一起一样，我需要的是这三个中断独立存在，需要怎么做
这里是我的代码
void MotorPwm_TripZoneOverCurrentConfig(uint32_t base, EPWM_DigitalCompareTripInput tripSource,uint16_t tzSignal)
{
    //
    // Action on TZ
    //
    EPWM_setTripZoneAction(base, EPWM_TZ_ACTION_EVENT_DCAEVT1, EPWM_TZ_ACTION_HIGH_Z);

    EPWM_selectDigitalCompareTripInput(base, tripSource, EPWM_DC_TYPE_DCAH);
    EPWM_setTripZoneDigitalCompareEventCondition(base, EPWM_TZ_DC_OUTPUT_A1, EPWM_TZ_EVENT_DCXH_LOW);
    EPWM_setDigitalCompareEventSyncMode(base, EPWM_DC_MODULE_A, EPWM_DC_EVENT_1, EPWM_DC_EVENT_INPUT_NOT_SYNCED);

    EPWM_selectDigitalCompareTripInput(base, tripSource, EPWM_DC_TYPE_DCBH);
    EPWM_setTripZoneDigitalCompareEventCondition(base, EPWM_TZ_DC_OUTPUT_B1, EPWM_TZ_EVENT_DCXH_LOW);
    EPWM_setDigitalCompareEventSyncMode(base, EPWM_DC_MODULE_B, EPWM_DC_EVENT_1, EPWM_DC_EVENT_INPUT_NOT_SYNCED);

    EPWM_setTripZoneAction(base, EPWM_TZ_ACTION_EVENT_TZA, EPWM_TZ_ACTION_HIGH_Z);
    EPWM_setTripZoneAction(base, EPWM_TZ_ACTION_EVENT_TZB, EPWM_TZ_ACTION_HIGH_Z);

    EPWM_enableTripZoneSignals(base, tzSignal);
    EPWM_forceTripZoneEvent(base, EPWM_TZ_FORCE_EVENT_OST);

}
void MotorPwm_TripZoneOverVoltageConfig(uint32_t base, uint16_t tzSignal)
{
    //
    // Action on TZ
    //
    EPWM_setTripZoneAction(base, EPWM_TZ_ACTION_EVENT_TZA, EPWM_TZ_ACTION_HIGH_Z);
    EPWM_setTripZoneAction(base, EPWM_TZ_ACTION_EVENT_TZB, EPWM_TZ_ACTION_HIGH_Z);

    EPWM_enableTripZoneSignals(base, tzSignal);
    EPWM_forceTripZoneEvent(base, EPWM_TZ_FORCE_EVENT_OST);
