PDC20246.htm seems to give enouth details the registers (I only had a quick
look at it), but PDC20247.htm doesn't give anything about registers at all.
So I don't know how to set up ultra-DMA modes.
Oh, it seems the 20247 is a chip that adds Ultra-DMA to a 20246. Strange ...
I'll have to read this more carefully :)
Thanks !
