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?
What e8053 processor?
There is no "e8053" listed at http://www.keil.com/dd/
Google gives plenty of hits for "e8053", but none on the first page is obviously an 8051.
If this is really so urgent, and you really want people to feel inclined to help you, don't you think you could at least make the effort to provide full information - and a website link?
