QEP Interrupt on Index

Hi

I am trying to have an ISR fired when the QEP Index signal goes 1, but no way

The ISR is called every time I move the rotor and not only when the index gives one

Where is the error:

  // init QEP Int ISR to QEP_Index_ISR
  HAL_Obj *obj = (HAL_Obj *)halHandle;
  PIE_Obj *pie = (PIE_Obj *)obj->pieHandle;
  EALLOW;
#ifdef J5
  pie->EQEP2_INT = &QEP_Index_ISR;
#else
  pie->EQEP1_INT = &QEP_Index_ISR;
#endif
  EDIS;

#ifdef QEP
	// initialize the ENC module
	encHandle = ENC_init(&enc, sizeof(enc));

	// setup the ENC module
	ENC_setup(encHandle, 1, USER_MOTOR_NUM_POLE_PAIRS, USER_MOTOR_ENCODER_LINES, 0, USER_IQ_FULL_SCALE_FREQ_Hz, USER_ISR_FREQ_Hz, 8000.0);
	// configure QEP Index Interrupt
	obj = (HAL_Obj *)halHandle;
	#ifdef J5
	QEP_Obj *qep = (QEP_Obj *)obj->qepHandle[1];
	#else
	QEP_Obj *qep = (QEP_Obj *)obj->qepHandle[0];
	#endif

	//QEP_clear_interrupt_flag( qep, QEINT_Iel);
	//QEP_enable_interrupt( qep, QEINT_Iel);
	EQep1Regs.QCLR.all = 0x0FFF; // clear Int Flags
	EQep1Regs.QEINT.all = 0; // disable int
	EQep1Regs.QEINT.bit.IEL = 1; // Set IE for Index
	//EQep1Regs.QEPCTL.bit.IEI = 2;	// Initializes the position counter on the rising edge of the QEPI signal (QPOSCNT = QPOSINIT)

	// Enable PIE group 5 interrupt 1 for EQEP1_INT
	PIE_enableInt( obj->pieHandle, PIE_GroupNumber_5, PIE_InterruptSource_EQEP1 );
	// PieCtrlRegs.PIEIER5.bit.INTx1 = 1;
	// PieCtrlRegs.PIEIER5.all = M_INT1;

	// enable the cpu interrupt for QEP interrupts
	CPU_enableInt(obj->cpuHandle,CPU_IntNumber_5);

the ISR

//-------------------------------------------------------------------------------------------------
__interrupt void QEP_Index_ISR(void)
{
	//GpioDataRegs.GPBDAT.bit.GPIO34 = 1- GpioDataRegs.GPBDAT.bit.GPIO34;
	//GpioDataRegs.GPBDAT.bit.GPIO39 = 1 - GpioDataRegs.GPBDAT.bit.GPIO34;
	HAL_toggleLed(halHandle,(GPIO_Number_e)HAL_Gpio_LED2);

    // acknowledge the QEP interrupt
	HAL_Obj *obj = (HAL_Obj *)halHandle;
#ifdef J5
	QEP_Obj *qep = (QEP_Obj *)obj->qepHandle[1];
#else
	QEP_Obj *qep = (QEP_Obj *)obj->qepHandle[0];
#endif
	  // clear the QEP interrupt flag
//	  QEP_clear_interrupt_flag( qep, QEINT_Iel);
	//EQep1Regs.QCLR.bit.INT = 1;	// Clears the interrupt flag and enables further interrupts to be generated if an event flags is set to 1
	EQep1Regs.QCLR.all = 0x0FFF; // clear Int Flags

	  // Acknowledge interrupt from PIE group 5
	  //PIE_clearInt(obj->pieHandle,PIE_GroupNumber_5);
	  PieCtrlRegs.PIEACK.all = PIEACK_GROUP5;
