    "home" might be the 3rd track elsewhere designated "zero" (the reference position).
    So, provided the QEI is configured accordingly, I expect it to set the counter to 0.

    If you know it by "index" ...  Some time ago I had incremental sensors sporting A, B, Z(ero).
    Naming differs, function doesn't.

    in datasheet writs that QEI has 4 inputs: QEA,  QEB, INDEX, HOME..do you mean INDEX and HOME has same function?

    I didn't read this specific datasheet. But I expect the answers to be in this datasheet or the QEI's FRM (Family Reference Manual).
    Maybe you should dig into this for details.
