This may not have any relevance to your problem, but case in point...
I had an IO pin on a LPC2102 not working.  I think what happened was 
that because my soldering iron was not grounded and I measure 60 VAC 
RMS between soldering iron and scope ground (which I think was 
connected while soldering to that IO pin connection) and I think I 
burned it out.  I just switched the software to another IO pin and it 
works now until I can replace the part.

Just be careful of differential voltages of soldering iron and 
grounds.  This is not the first time in my life I've had this kind
of problem.
