    I believe you are missing some info about SFR ports. Port 7 is SFR 0x96 which can only be accessed via a direct instruction. The XBYTE macro is used to address XDATA memory via a pointer.
    There is no indirect access to the SFR memory area.
    Suggest that you review memory areas idata,data, code and SFR for more info.
