MSP430FR6989: Problem on Water Meter Reference Design for three LC Sensors, Using Extended Scan Interface (ESI)

Dear Sir/madam,

I bought a EVM430-FR6989 and would like to implement the Water Meter Reference Design for three LC Sensors, Using Extended Scan Interface (ESI)

i download the package and run , however i encounter the following problem:

1) the demo didnt work, the counter is always 0 whatever i try to locate my motor board for what distacnce. Any idea?

2) i try to use ccs to reload the sample program , however the result is the same.

Any idea?

3) i try to debug the program ,  setting the breakpoint and seems the program does run , however it  never fall into the case 0x0c

__interrupt void ISR_ESCAN_IF(void)
{

   switch (ESIIV)

 case 0x02:  if (ESIINT1&ESIIE1)

                {    ESIINT2 &= ~ESIIFG1;                     // clear the ESISTOP flag

                    if(ReCal_Flag&BIT6)
                    {TA0CTL |= TACLR;                       // Reset Timer to prevent abnormal time out.
                    TA0CCTL0 &= ~CCIFG;    }

                    _low_power_mode_off_on_exit();           // exit low power mode;
                }
              break;

   case 0x04:  break;
   case 0x06:  break;
   case 0x08:  break;

   case 0x0A: break;
   {case 0x0C: if(ESIINT1&ESIIE5)
                               {    ESIINT2 &= ~ESIIFG5;                // clear the Q6 flag

                                      if(ReCal_Flag&BIT6)
                        {TA0CTL |= TACLR;                   // Reset Timer to prevent abnormal time out.
                        TA0CCTL0 &= ~CCIFG;    }

                        if(ReCal_Flag&BIT7)
                        { ReCal_Flag |= BIT6;    }           // to do runtime calibration with AFE2

                        if(Status_flag&BIT3)                // Check for completion of Calibration of DAC
                        {                                    // If yes, LCD is to display the rotation number

                            rotation_counter = ESICNT1;     // for every complete rotation, there are 6 states change and so add +1 six times

                            if (rotation_counter < 0)
                                {rotation_counter = -1*rotation_counter /6;}
                            else
                                {rotation_counter = rotation_counter / 6;}

                            lcd_display_num(rotation_counter,0);
                        }


                        _low_power_mode_off_on_exit();       // exit low power mode;

thanks
