I'm looking. It must have been online because it's neither one of the copies on my hard drive.
If I remember correctly, they showed driving the SCLK pin with an RC delay to the RCLK pin (a 100 ohm resister between the two pins and a 200nf cap' on the RCLK pin). This allows data to stay in sync' instead of being 1 bit behind as would be the case if you tied SCLK anr RCLK directly together.
Unfortunately this wouldn't be a 2 pin interface because you would still need to drive the LCD 'E' line. I apologize.
I'll keep lookin' online for that data sheet.
