See http://www.aeolusdevelopment.com/Articles/download.html Look at the 
newlib-lpc source for an example of using the timer for generating 
micro-second delays.  There is also an application note 
http://www.aeolusdevelopment.com/AppNotes/LPC210X/an-timerperformance.pdf 
that describes the performance of the timer and one 
http://www.aeolusdevelopment.com/AppNotes/LPC210X/ConfiguringTimer.html 
describing how to adapt it for different clock rates.

The code was developed for the 2104/5/6 members of the family but should 
work for other members since most (all?) share the same timer peripherals.
