Before you posted this, I had hunted for this capability in the reference
manual last night, and didn't find anything. Now that I know it's there
I'll look again. Thanks. By the way did you get your sensor working?
I second the question about the DREQ0/DREQ1 (aka GPIO19/GPIO20). Does
anyone know if the gumstix uses these internally?
