So my suspicion that TI has made a fuckup on their pin labels is gathering evidence:
Along with the question I linked in the other post, it really looks like they are calling analog ground DGND, and that they call digital ground AGND.
They even say things like: “oh yeah, the SPI pins have pulldowns to AGND”. Like wtf.
I really want this to be the case, that it’s just a name swap mistake (and they roll with it because it’s burnt into so many people’s designs by now), and not some really crappy internal cross coupling of analog and digital signals in their chip…
