LSMDLHC: What is the function of the REFERENCE_A register (0x26)?

 According to the datasheet: "Reference value for interrupt generation.".

Is this intended to be used to subtract off say gravity or some other constant value? Is this a scalar value applied to all three dimensions?

Hi @NSand.1​ , are you referring to LSM303DLHC part number? Yes, it is a threshold reference value, but should not to be used because you can separately define thresholds for both INT1 and INT2 in the proper INT1_THS_A (32h) and INT2_THS_A (36h) registers. Regards
