    Default Low Voltage Programming - possible solution?

    Just an idea: would it be possible to overcome the code protection issue by programming the PIC with a Low Voltage method?

    Actually, I've never done this so I don't know how to do and and if it would work.

    BTW: I put the µC on my breadboard with "nothing" connected to it appart from a 0,1µF cap between Vdd and Vss.

    Default Bulk erase (Chip erase)

    Hello,

    Does anyone know what, in the PIC's programming process, is different if I program an application or if I just "bulk erase" it?

    Is there a way to do some kind of "manual bulk erase" using another PIC programmed accordingly to the "Flash Memory Programming Specification"?

    I just can't understand that the "bulk erase" command doesn't work if I can normally program the chip....
