I want to run all 16 channels.I have some uncertain on DAC Control 1 and DAC Control 1 register. I know the serial format of the second ad1934 is TDM (daisy chain)   , and how the first ad1934? I select the 16 channels in register  DAC Control 1 of second ad1934,and the first ad1934 is 8 channels? Thank you very much  for your reply.
