I connected a 128x64 ks108 based lcd to XMEGA with 5v supply for lcd and 3.3v for XMEGA. There is a read function in lcd library, which reads data from lcd to microcontroller. According to 5v supply for lcd and direct connection of Data bus between lcd and XMEGA, I expected a possible damage to lcd or XMEGA. But surprisingly it works fine. I also tested this for ATMEGA64A and it also works without damage.
