Looking at this image from my scope, would you agree that from top to bottom it's DAT0 (yellow), CLK (purple), CMD (cyan)?
I'm guessing this on the basis CMD is just briefly at the begging/end, the CLK is constant while data is transferring, and DAT0 is on but much less consistent.
Incidentally, at the about the 3/4 mark on the first screenshot, no idea why all three signals suddenly look 'fuzzy'?
