Which pins are necessary for proper communication. I connnected only Dvdd, Dgnd, Rst, DIN, DOUT, SCLK, /SYNC, AD0=DGND, AD1=DGND. I have no idea what is wrong. At Dout i get only 0xFFFF when i want to read status register. I'll appreciate any suggestion.
To read status register, i'm sending 0x980000 and next (NOP) 0x1C0000 and i get 0xFFFF. I have looked at SPI waveform using oscilloscope and everthing looks ok, bits from left to right 1001 1000 0000 0000 0000 0000(0x980000) and 0001 1100 1110 0000 0000 0000 0000(NOP)
