which order channel data is presented on the DOUT line. This information is
provided in the datasheet only for the parallel interface.
In the case of using a single DOUT line (DOUT A), the data is output in
ascending order V1, V2, V3, V4, V5, V6. There is an application note AN-893 on
topic of : Configuring the AD7656/AD7657/AD7658 for Serial and Daisy-Chain
Interface Modes of Operation. This application note shows the typical read
sequence using all options for channels/single or multiple DOUT lines.
This note also covers the daisy chain mode of operation. Both subjects are not
covered sufficiently in the datasheet. See AN-893 at www.analog.com
