External capacitors
The C1 and C2 external capacitors should be low SR value, ceramic type construction (typ
recommended value 200 mOhm). Reservoir capacitor C1 is nominally 4.7 μF in
capacitance, with the set/reset capacitor C2 nominally 0.22 μF in capacitance.
The device core is supplied through the Vdd line. Power supply decoupling capacitors
(C4 = 100 nF ceramic, C3 = 10 μF Al) should be placed as near as possible to the supply
pin of the device (common design practice). All the voltage and ground supplies must be
present at the same time to have proper behavior of the IC (refer to Figure 11).
The functions of the device and the measured acceleration/magnetic field data are
selectable and accessible through the I²C / SPI interfaces.
The functions, the threshold and the timing of the three interrupt pins (INT_G, INT1_XM and
INT2_XM) can be completely programmed by the user through the I²C / SPI interfaces.
