Is MISO pin goes tri-state when it's CS is not asserted ?
Thank you for your answer,
My SPI bus is shared by many parts ( A/D and D/A convertr, fash memory,... and a digital isolator ).
I guess my problem comes from the digital isolator. ( See that: http://ez.analog.com/message/44065#44065 )
Yes, the DOUT/RDY pin of AD7792 is tristated when the /CS line goes high or not asserted. For additional information, you can refer to this discussion link.
