Lpc2000

Hello,

I was actually looking for a description of this register, it does not
appear to be documented anywhere that I know of. 

The other question I have is if setting this register is even
necessary, most examples that I have run across don't set this
register.  The book mentioned previously says that this register must
be set.  Just trying to figure out what I really need to do to make
PWM work reliably.  Any recommendations, examples that work, etc?

Thanks.
