Triaxial, digital acceleration sensor
Figure 2: Any motion criterion (middle graph) is determined from digital filter output (upper
graph) and depends on bandwidth settings: for example for any_motion_dur=01b and
bandwidth=110b (1.5kHz), we have 2*bandwidth=3ksamples/s which leads to reaction for
interrupt activation of 3*333µs = 1ms and a minimum any motion interrupt duration of 3*333us =
1ms (see lower graph).
If lower bandwidth is selected i) the digitally filtered values (lower noise) are taken for the
verification of the any motion criterion and ii) the time scale to evaluate the criterion is stretched.
Thus adjusting the bandwidth, the any motion threshold, the any motion duration as well as the
full scale range enables to tailor the sensitivity of the any motion algorithm.
