These pattern effects are not documented on the AY8930 system page:

2Cxy: automatic noise frequency
2Dxx: whatever this is
2Exx and 2Fxx: write to I/O ports (presumably can just be copied from the 8910 page)

Both the AY-3-8910 and AY8930 instrument pages are missing these macros:

Also, I think there should be some clarification on the default/reset values for the 8930 noise masks.

oh, 2Cxy is missing from the 8910 system page as well
