Melexis recommends using the multi-slave application diagram
as shown on the right.
The SCLK, MISO and MOSI wires interconnect the slaves with
the master. A slave is selected by its dedicated /SS input. A
slave MISO output is in high-impedance state when the slave is
not selected.
Slaves can be triggered synchronously by sending Sync pulses
on the different /SS. The pulses must not overlap to avoid
electrical short-circuits on the MISO bus.
