I was trying to monkey with a graphics library I have to drive a 240x64 T6963C-driven LCD.

At one point I had my graphics all screwed up, drawing off the screen. The thing is, I thought I saw a gray "halftone". I was not aware the T6963C had any capacity to draw anything but black or white! I was in the middle of fixing it so I got the graphics working again, but was unable to replicate that effect.

Was I just seeing things, or is there actually a halftone support in there? I don't recall seeing anything on the spec sheet to that effect. I suppose the graphics could have been writing and clearing that portion of the graphics so fast it appeared grey, but I have a hard time believing that, the flicker would have been quite noticible.
