I think this should be it. Seems a bit unusual, kinda rotated by 90° compared to a lot of display drivers.
I'm not sure whether you have to reset the column and increment the page after each page, but I think so. The spec doesn't mention the column wrapping around (it says it "tops" at 83h which is the last column, but doesn't say it wraps to 0...). As for the page, it doesn't state that the page is incremented automatically either.
