One more question concerning the communication.
RDY/ pin is going low when a data is available. (And high as data is readed or is a new conversion is achived).
In some parts, DRY/ pin is coupled with DOUT.
Is the RDY pin (and DOUT) going low only is the part is selected by the chip select?
It comes on the discussion because I said to tream that using AD7195 (part with RDY/ coupled with DOUT) we should use 2 separated SPI bus to connect 2 parts to µC.
A member said that RDY/ should go low only if part is selected.
I do not agree because RDY could be use for as an interruption input of µC (so even if the part is not selected).
