eCAP CEVT1 and CEVT2 interrupt initialization

Hello, 

I am trying to configure eCAP module on TMS320F28027 in Rising/Falling edge Delta timing mode in order to calculate the pulse width. 

However, only one of the interrupts (CEVT2 @ ecap2_isr) routine gets triggered and it gets triggered only once. Please refer to the code snippet below. Any thoughts?

interrupt void ecap1_isr(void)
{
    printf("\n\r In ECAP1 ISR\n\r");

    // Read CAP1 time base counter at CEVT1
    cap_t1      = CAP_getCap1(myCap);

    // Clear eCAP Interrupt
    CAP_clearInt(myCap, CAP_Int_Type_CEVT1);
    // Reenable CAP1
    CAP_rearm(myCap);

    printf("\n\r Cleared CEVT1 INT \n\r");
}

interrupt void ecap2_isr(void)
{
    printf("\n\r In ECAP2 ISR\n\r");

    // Read CAP2 time base counter at CEVT2
    cap_t2      = CAP_getCap2(myCap);
    // Calculate pulse width
    cap_period  = cap_t2 - cap_t1;

    printf("%d, ", cap_period);
    printf("%d Hz \n\r", (40000000/cap_period));

    // Clear eCAP Interrupt
    CAP_clearInt(myCap, CAP_Int_Type_CEVT2);
    // Reenable CAP1
    CAP_rearm(myCap);

    // Clear PIE Interrupt
    PIE_clearInt(myPie, PIE_GroupNumber_4);

    printf("\n\r Cleared CEVT2 INT \n\r");
}

void cap_init()
{
    // Register interrupt handlers in the PIE vector table
    PIE_registerPieIntHandler(myPie, PIE_GroupNumber_4, PIE_SubGroupNumber_1, (intVec_t)&ecap1_isr);
    PIE_registerPieIntHandler(myPie, PIE_GroupNumber_4, PIE_SubGroupNumber_1, (intVec_t)&ecap2_isr);

    // eCAP1 on GPIO5
    GPIO_setPullUp(myGpio, GPIO_Number_5, GPIO_PullUp_Enable);
    GPIO_setQualification(myGpio, GPIO_Number_5, GPIO_Qual_Sync);
    GPIO_setMode(myGpio, GPIO_Number_5, GPIO_5_Mode_ECAP1);

    CLK_enableEcap1Clock(myClk);
    // Disable all eCAP interrupts
    CAP_disableInt(myCap, CAP_Int_Type_All);
    // Clear all eCAP interupt flags
    CAP_clearInt(myCap, CAP_Int_Type_All);
    // Disable CAP1-CAP4 register loads
    CAP_disableCaptureLoad(myCap);
    // Ensure counter is stopped
    CAP_disableTimestampCounter(myCap);

    // Configure CAPx for Capture mode
    CAP_setModeCap(myCap);
    // Configure peripheral registers
    //CAP_setCapOneShot(myCap);
    CAP_setCapContinuous(myCap);
    // Set MOD4 Stop/Wrap value
    CAP_setStopWrap(myCap, CAP_Stop_Wrap_CEVT2);
    // Rising Edge
    CAP_setCapEvtPolarity(myCap, CAP_Event_1, CAP_Polarity_Rising);
    // Falling Edge
    CAP_setCapEvtPolarity(myCap, CAP_Event_2, CAP_Polarity_Falling);
    // Reset capture event 1
    CAP_setCapEvtReset(myCap, CAP_Event_1, CAP_Reset_Enable);
    // Reset capture event 2
    CAP_setCapEvtReset(myCap, CAP_Event_2, CAP_Reset_Enable);

    // Enable sync in
    //CAP_enableSyncIn(myCap);
    // Pass-through
    CAP_setSyncOut(myCap, CAP_SyncOut_Disable);

    // Enable CAP1-CAP4 register loads
    CAP_enableCaptureLoad(myCap);
    // Enable CAP CEVT1 counter
    CAP_enableTimestampCounter(myCap);
    // Arm one-shot
    CAP_rearm(myCap);
    // Enable CAP1-CAP4 register loads
    CAP_enableCaptureLoad(myCap);
    // Enable interrupt on CEVT1
    CAP_enableInt(myCap, CAP_Int_Type_CEVT1);
    // Enable interrupt on CEVT2
    CAP_enableInt(myCap, CAP_Int_Type_CEVT2);
