The BDI2000 works very nicely on 82xx processors.
The 82xx debug unit is the standard COP interface,
completely different from the 8xx debug interface.
Stop looking for a DER on the 82xx, plug in the
BDI2000 and use it.  Make sure you understand all
of the features of the BDI2000, as even on the 8xx
you should not be worrying about the DER. Let the
BDI2000 configure all of that accordingly based upon
what you are asking it to do.
