My understanding is you don't get both.. you get one or the other. Mode 1 for slow, but no ghosting and known state (you should always START with this), or Mode 2 for faster, some ghosting. And according to what I've read, make sure you revert to full refresh regularly to keep the screen "healthy"
From the spec, I see parameters B1 and B9 for command 0x22... but I don't understand their use. I use CF for a Mode 2, and if you don't call the command it appears to default to Mode 1 (after reset anyway)
