Help with LD7222 display driver

I'm currently trying to interface an OLED shield to a PIC18F2550, but I'm having trouble trying to figure out how the display driver works.
Its a COG display driver: the LD7222 from LTD. The problem is, I can't seem to find the data sheet for this controller and all I have to work with is the pdf file I've attached:

CanView attachment NVK-160SC002F-S-0100.pdf

I'm not having any problems with the MCU, just trying to figure out the timing diagram for controlling the display and how the commands work for this particular chip since I can't find the data sheet. LTD doesn't seem to have any data sheets for their products on their site as well, and the LD7222 doesn't seem to be on their catalog anymore (only the LD7221 and LD7223, but still, no datasheets).

Do all COG display drivers work the same? If so, can anyone point me to a tutorial or datasheet for a chip similar to the LD7222? Thanks in advance.

Have you gotten answers to your questions about the cog driver? A LD7222 datasheet has been mailed to me in response to my enquiry. If, in case, you still need one, just send me an email.

Regards.

Any datasheet on this LD7222 driver? :S
