Section 6.2 of the data sheet says that ''SPC,SDI,SDO are common'' however there are 2 different SDO pins, SDO_A and SDO_G. Has anyone tried connecting the two SDO pins on the target board? 

Does anyone know if I2C mode always active when the CSx pin is HI? If so how do you prevent the I2C module for erroneously receiving a command from other devices that may be operating on the SPI bus?

Thanks

    is confusing

    on this issue.

    Furthermore

    evaluation

    board

    STEVAL

    -

    MKI109V2

    and

    ''Unico

    GUI''

    using

    I2C

    protocol

    .

    Best regards

    agree. so confusing. i am not sure that it is possible that i connect two SDO line together since i enable / disable  Accere/Gyro and Magnet seperately.
