[DSP-10] KDSP10 Info

[Doug Bade]

Hello Luis;
         I appreciate the offer, however I am running the new DSPx board 
and the 2 (UHFA and UHF3 )pieces of code are different , which makes it 
less than convenient at this time to use modified code. I guess I could 
re-compile, but a hardware solution is acceptable to me. I may even order 
another SOIC so it takes up less space. Thanks for the offer anyhow.. I 
also suspect it adds a little delay to the clock routine to make sure all 
other levels are steady state before the clock triggers load. It seems like 
it should be fine this way, however I still need to go back through the 
feedthru cap and reconnect all that back to stock...
