int_orient_refy_7_0
int_orient_refy_7_0: lsb of y-axis reference for orientation change evaluation
lsb of y-axis reference for orientation change evaluation
the value is a signed integer, either provided by the host (orient_refu=0) or automatically
the interrupt calculates abs(acc_x/y/z-int_orientch_refx/y/z)>orient_thres to determine
whether activity is sufficiently high on the x/y/z-axis to cause an interrupt trigger
int_orientch_refy = int_orient_refy_7_0 + 256*int_orient_refy_11_8
