Figure 1. The MD band-pass filter's frequency response.
The absolute value of programmable Threshold Level (TL) is 0 < |TL| < FS g (FS is sensor full
scale measuring range). NOTE: Due to power consumption optimization, the step size between
each step and axis is not the same, see section 3.4 for threshold level details.
Motion detection is sensitive to directions according to Figure 2,
Figure 2. MD Sensitive axis
where X, Y and Z represent Component axis and V1, V2, and V3 MD sensitive axis. Correlation
between axis is V1 = X+sqrt(2)*Y, V2 = X -Z and V3 = X .
