LSM6DSO Register - WAKE_UP_THS - 0x5B

[Dude]

Hi, 

I am looking at the LSM6DSO device, and I am unclear what the "USR_OFF_ON_WU" bit does in the "WAKE_UP_THS " register. Does this bit: 

1. Drive the Wake-Up function with offset corrected accelerometer data? 0 means not offset corrected, 1 means offset corrected?
2. What does this have to do with High-Pass Filtered Data? Does this bit actually set whether Lowpass or Highpass information is used to drive the Wakeup Function? 

Can someone please provide clarity? 

thanks
