DDRE in Atmega162 and LCD

Hi,

I am using the atmega162 with a T6963 LCD and GCC compiler.
The control bus are in PORT C and data bus PORT A.
I am also unsing PORT E pins 1 and 2 to a external circuit(chip select
to 2 4514N).

The problem:
When I set the DDRE pins 1,2 to output, the LCD get trash!
I write on lcd and all is fine, but after to assign 'DDRE = 0x06' and
write again the LCD is defaced,

(Can you reply in english? thank you)
