    Default Re: understanding I2CWrite optional address parameter?

    Attached is also a screen shot of one of the I2C transactions.
    I was surprised to see two read transactions followed by one write transaction.
    Especially because there is no IC2READ occurring in the code.
    I'm simply writing one value to the IO chip.
    So I wonder if the chip is programmed to return the two READ transactions - or is PBP3 doing that as part of the IC2WRITE function?
