Hi,  
I am working with the Lsm9ds0 sensor and i would like to properly configure the Click recognition.
After reading the datasheet I manage to rise an interrupt on a click but i still have a question about this functionality:
    What is the unit of the threshold on the CLICK_THS register, is it 16 mg per LSB as in the Act_THS register or is    depending of the range of the accelerometer ?

Secondly I would like to configure a High-Pass filter in order to reduce the noises on my click detection. It seems to be possible using the CTRL_REG0_XM, REFERENCE_X and REFERENCE_Y registers.


                                      
Could someone confirm me that the « Reference value » mentioned on those register’s description is the cut-off frequency of the filter.

Regards,
