    ok, that is why i was not able to observe dataregister (S0SPDR).
    Today I on my UART and send each responce on hypertermanil.I observe that when i send my write opcode (0x87)than at same time i read responce and send it to hyperterminal I got OxFF reponce on hyperterminal.what it means? Is opcode is appropriate reach to dataflash or not?
