Lpc2000

I want to be able to update our LPC2104 firmware with a UART 
interface.  It seems like the UART is setup to rely on INTs for 
transfer.  Given that the code must be executed in RAM, I suppose the 
INTs for the UART must be setup in RAM as well.

Are there any example files around of this kind of RAM code setup for 
moving the INTs into RAM.  I see it talked about all the time in the 
lit but have not seen any code examples. 

Or the easier way might be to run the UART without the need of INTs.  
Anyone done any of this?

Thanks,  Chris.
