I have an AD7689 chip which I am programming to sequence between 8 channels through and SPI-DMA setup via a BF592 processor. I built the front end analog and conneted the digital control lines. When I set the seuqnecer of the AD7689 to sequence between channel 0 and 1, I get the output that I expect (i.e. have the correct data in the DMA buffer that I have setup). When I switch between channel 0 and 7, I start getting rubbish data.


Has anyone had such a problem. Do you have any code the fixes this issue?
