External capacitors
The device core is supplied through the Vdd line. Power supply decoupling capacitors (C2,
C3=100 nF ceramic, C4=10 µF Al) should be placed as near as possible to the supply pin of
the device (common design practice).
All voltage and ground supplies must be present at the same time to achieve proper
behavior of the IC (refer to Figure 13).
The functionality of the device and the measured acceleration/angular rate data is
selectable and accessible through the SPI/I²C interface.
The functions, the threshold and the timing of the two interrupt pins for each sensor can be
completely programmed by the user through the SPI/I²C interface.
