Hi Zhou,

I have moved this question from the Software Modules and SDKs community to the SigmaDSP Processors and SigmaStudio Development Tool community. Please continue the discussion here.

Hi Zhou,

The serial port control registers for the AD1954 are listed and described on pages 20 - 22 of the datasheet.

From looking at the control register available settings, there is no way to change the DAC serial port from a slave to a master; it is always a slave for LRCLK and BCLK.

At various places through the descriptions, there are references to (default) modes. These would be the settings upon powerup of the part. If a default is not designated, I would assume that a value of b0 or b00 is the default.

Best regards,

Coleman
