AMC1306M05: How to implement AMC1306/ TI delta sigma modulators?

Hi there, 

I am working on a project using TI delta sigma modulators, AMC1306 to sense current and AMC1336 to sense voltage, and am struggling to understand how to read the digital output. Currently, I am using an STM32 to supply the CLK and apply a Sinc3 filter with 256 oversampling ratio to DOUT. The digital filter is filling a unit32 buffer via DMA however after this step I am unsure as to how this is converted to a decimal reading. This is my first time using delta sigma and I find the documentation on how it's implemented to be scarce however my understanding is that the binary in my buffer is that from the PDM and so I need to find a way to process this bit stream by counting the number of 1s and scaling depending on my configuration.

So in summary my question really is:

Are there any examples/ docs on how to read data from these chips or tips on how I should go about this?

Thank you,

Tom
