My understand (still untested) is that you have to take TSC low _and_ flip
some register bits to get into test mode, at least on the '332.

The original TPU book has a section with some details on the debug hardware
built into the TPU.  There's a copy on the web--google for "TPU microcode
reference" ought to do it.

There's a free dos based TPU debugger (TPUBUG) from Moto out as well, but
I've yet to fire it up.  The readme file for it looks promising.

Charles Melear offered to send TPU info to anyone with a mailing address
not 5 days ago on this very list--you should take him up on it.  Good stuff
in a box.
