#73363 - p89v51rd2 secutity bit - serial number
hello,
I am little confused with P89V51RD2.
if I program (with flash magic) security bit I can't erase or program again the memory flash (via ISP).
The question is:
If I program serial number and leave the security bit
unprogrammed (to update program in the future),code can be recovered via parallel programmer?
(sory for my bad english)
Thanks
Lambros
