I found a data-sheet for TUA6034 at http://pdf.datasheetcatalog.com/datasheet2/4/084ailjhz4xq79otdj14u5laz3py.pdf (found at http://www.datasheetcatalog.com/datasheets_pdf/T/U/A/_/TUA_6034-T.shtml) At the 46th page of the PDF file I found some programming instructions. It may be a good start for write driver for this tuner? I will try to find programming instructions to how can I write driver, but if you (or anybody) have any good start-up instruction for me I am very glade for it.
