Having a problem wiring this up and getting initialisation to work

What I'd really like is a schematic for the pcb or even a block diagram to try to understand how this device works.  What is the purpose of the Atmel device, how does the backlight actually work, why are the drawings provided for this part so different to the actual part (see attached image and compare with website image)?

Do all the ground connections require to be connected?

We have an existing product that uses a PIC32 with16 bit data (bit0 and bit9 set to zero) using PMP and I need to connect this device instead.

What is the initialisation sequence for this device?  Is there an example other than the one on the product web page?
