See http://www.open-research.org.uk/ARMuC/index.cgi?LPC2100Tips

It has pointers to early measurements of the pin toggling and an 
explanation from Philips.  Both are threads from this group.  Some newer 
devices are better.

I did once get a very short pulse out of an LPC as a result of a timing 
glitch/race but I doubt that that is useful.
