    Hello,
    I am having some difficulty understanding how to address the TCA9544a multiplexer. I am using an XMEGA256 microcontroller in which I would like to address the multiplexer using TWI port E. I have 4 HMC5883L sensors connected to the 4 outputs, however I am confused as to how I should be addressing each sensor individually. Any help with this is appreciated.
    Thanks

    Very simple. Code to the datasheet.
