I am using the AD7682 in Read/Write Spanning Conversion mode without busy indicator (page 34 of datasheet). It mentions in this section that the first 15 SCK falling edges clock out the conversion results starting with MSB – 1. However, the timing diagram on the same page shows data out starting at MSB.
Using my tools, I am getting 15 bits of data starting with MSB -1 down to LSB, so I assume that the timing diagram has a typo in the SDO line, and it should indicate MSB – 1 instead of MSB.
Anyways, my question is, how do I read the MSB in the RSC mode without Busy Indicator?
