Once upon a time back in the days of pirate smart cards i used to be able to read from pics even if the CP fuse was blown (16?84).
Is this still a problem on later pics? or are they pretty secure.
My second question is, if pics can still be copied once the fuse is blown is it possible to use code to have a pic erase itself if it is removed from a pcb. e.g.If I pin was not tied to ground and power was applied could I make it erase itself?
I assume I could use a bootloader of some sort to do this?
