HI. I am a Newbie. sorry for my english.
I bought a enhanced programmer to use mostly with AT28C64B that i use in some machines in my work. Instead of programming with a console, that takes me about an hour, i want to copy the content of another eeprom. I make a copy and verify and its ok. I replace the new programed eeprom and it works fine, but i can not change data (parameters) with my console at work. The new eeprom seems to be write protected. Where can i enable / disable this in the programing software or chip ?
Do you understand what i mean? Please help. Thank you!
