pleas ansewr now for me is usrgent!!!!!!!!!!!!!!!!!!!!!!
I read the datasheet and still donot understand the function of the 3 modes of Lock Bit...It use to prevent other from read out the flash & eeprom ? Or it use to prevent other rewrite the flash & eeprom ? ..
Can my code protect the Flash memory part while allow the eeprom data to be read out ?
I usually release my chip with lockbit so no one can't read the flash. But if I need to update or bug fixed, I can erase that chip and write again. With the lock bit set, my program can read and write value to the EEPROM. But someone can't read it via ISP programmer.
what are wrong?
Who do you think will 'urgently' hunt up whatever the document you refer to is.
What is your problem, besides urgency, in helping those that MAY help you.
You are referring to some chip with incomplete information if anyone google on "data8052.pdf chaptar 5 for the e8053 porcessor" what are they going to get? if you, in your urgency, had included a link I might have had a look.
