ADAU1761, output DIG0 usage

Question asked by kenlam on Jun 10, 2011

I am working on a project using IO > Output to export data to external MCU.

I found the output port has DACx and DIGx selection.

Can I know how can I read the DIG0..DIG7 by external MCU?  What is the address location and data format for the DIG0..DIG7?

 

I found some document suggest to use "Basic DSP > DSP Functions > DSP Readback" block to read signal level.

Can I know what is the difference between these two reading methods?

Which method is better if I want to read the audio envelop from external MCU?

 

Thanks in advance.
