Thanks to Bob Ammermann and Tony Nixon for his replies.

Anbody that own a Microchip's ICD can read the position 0x2004
in the target PIC (with debug code enabled)? I think that reading this
location
can validate (or not) the Tony's hipotesis about 13 bits loading
of the PC (please read below).

Meanwhile, I try to build a ICD using the information provided for
Patrick Touzet in his pages:

Best regards.
