Problems with initialization of VL53L1X

Hi, I am looking for a ToF sensor using VL53L1X.
We are currently developing a ToF sensor using VL53L1X.
I have a question about the sample API VL53L1X_UltraLowPower you are using.
Whenever I execute VL53L1X_ULP_CheckForDataReady within VL53L1X_ULP_SensorInit(), it always TimeOut.
After examining the contents a little more, it seems that the problem is caused by the difference between the values of &temp and int_pol obtained by the VL53L1X_ULP_GPIO__TIO__HV_STATUS command. (This is the location in the picture).

In other words.
・What does it mean to do this setting
・What does the value of temp mean?
・What does &temp return?
I need answers to these three questions. The microcontroller in use is EFR32MG22

Also, if I use VL53L1X_ULP_GPIO_HV_MUX__CTRL, 0x11 is returned and int_pol is set to 1. Please let me know if this is even the correct behavior.

 

I would be glad to answer your questions!

Best Regards.
