The board is designed to have one MEMS assembled on the board although I
SPI allows more devices to be used simultaneously. Care should be taken, however
with the RDY/INT pins, as they are shared.
When U10 LD2980CMxx is not assembled use R100 instead. For low voltage MEMS
When U11 LD2980CMxx is not assembled, use R110 instead. For low voltage MEMS

If they are not necessary, use resistors R80, R81, R82, R83 instead.
If they are required, use operational amplifiers with the following resistor
configuration.
R80, R81, R82, R83 - not assembled
R84, R86, R88, R90 - not assembled
R85, R87, R89, R91 - assembled with 0R.
To alter the gain of the operational amplifiers, use following resistor configuration.
R80, R81, R82, R83 - not assembled
The gain is determined by configuration of R84, R86, R88, R90 and R85, R87,
R89, R91.
In all cases it is recommended to have assembled filtering capacitors C84, C85,
C86, C87. Default is 10 nF, but this can be changed according to the required
filtering features.
The unused interface must be selected as floating input or third state.

When using SPI, each device has its own chip select.
