The pcb configuration now looks like this.

We are going to use Figure 19 in TYPICAL CHARACTERISTICS. (only use HPLCOM and HPRCOM)

.(https://www.ti.com/lit/ds/symlink/tlv320dac32.pdf?ts=1630621395045&ref_url=https%253A%252F%252Fwww.google.com%252F)

Any help would be appreciated if there are any registers that need to be additionally set or if there are bad registers. 

I need help with initial register setup

thank you!

    Hi Gwonsang,

    The description of the registers looks OK to route the DAC signals into the HPxCOM outputs, although I'm not clear on the syntax being used to verify each bit value.
    Are these all the commands you're using to initialize the device? What about your clock settings? What is your MCLK, BCLK and WCLK frequencies? Are you configuring clock dividers somewhere else in your script?

    Best regards,
