When I use ad9680, the configuration is M = 1, F = 2, L = 2. At this time, ad9680 selects converter A as the sampling channel by default. Since the impedance of converter A does not meet my requirements, I want to use converter B, but I don't know how to set it up. I tried to turn off converter A to power it down, but it had no effect, so I would like to ask how to use converter B to sample the data when a converter is selected.
Please reply me as soon as possible。
I found that I set 0x564 to make the converter channel switch enable, then set 0x008 to set channel a, set 0x002 down channel a, set 0x008 channel B, set 0x002 to work, and then went on to configure the data, finding it is useless. Either at serdou0-1 or serdout2-3
