I just stumbled across a method to read out PIC code in any PIC that uses
the XNOR/XOR scrambled readback method when the PIC is protected. It is
here:

I know that more recent PICs read out as zeros when protected. I hope that
you out there who rely on PIC data protection know this.

PS: Apologies if you already know this.
