MSP430F5529: Communication with the LMP91002 over I2C is always stuck in the __interrupt void USCI_B0_ISR(void) interrupt

Hi team,

#pragma vector=USCI_B0_VECTOR
__interrupt void USCI_B0_ISR(void)

  case  4: break;                                                              // Vector  4: NACKIFG
  case  6: break;                                                              // Vector  6: STTIFG

}

Always stuck in case10 in the TI_MSP430_i2c_USCIB0_5xx.c file, The pull-up resistor has been added to the I2C and use the official LMP91002 driver library. The customer would like to know what's the possible reason for that.

The source code is as follows: https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/55/MSP430_5F00_Project.zip

Could you help check this case? Thanks.
