Mega2560 eeprom pin addresses??

Hello,

I need to control some pins from my eeprom on an Mega2560 r3 and I can't seem to get the pins reacting. I looked at the datasheet and I saw pin 29 starts at 0x00 and some other pins go on til 0x20, but still to no avail. I'm not sure if I'm selecting the wrong address to write to or not (hopefully not). Any advice would be great. Thanks in advance!

Can you explain what this means any maybe post the code you have tried. At the moment this does not make sense to me.
