Which pin is busted? 2,3 or 20,21 Not sure if this can disable DCO1 
but it sure looks like it could??? 
I've had good luck soldering to busted pins even if they were flush 
with the side of the chip. Just remember the heat will now be much 
closer to the inner workings. I also have the pdf datasheet for the 
NJM2069 around here somewhere. 
Good Luck, Fran
