This is a bit of following question on this post. I am using a AD7608: every time a conversion is initiated (CONV), once the BUSY signal indicates the conversion has completed, reading the 8 channel data on the SPI bus is initiated with /CS and clocking the SPI MISO line. Now typically one would read 8 channels * 18 bit = 144 bits on the bus.
In this particular case, I am only interested on a subset of the 8 channels, Let's say 4 channels, which corresponds to 72 bits.
- Can I reset the /CS after only 72 bit have been transferred without issue?
- Can I reset the /CS and immediately initiate a new CONV without issue?
