I have 2 DIP and some smd parts. All are new and not used before (yesterday
I used one :).
But in the picprg2.3b there is no flash erase command (at least in menu, I
didn't look into src).
If the copy protection bit is set to 0 the part is unreadable, but when it's
not touched (I didn't program
ANY conf bits- I want the program only burned not running) the flash should
be readable.
Am I right?
