LPC32xx trying to get Standard UART Rx interrupt after single byte

Am a bit confused by the interrupt behavior of the standard UART (specifically UART 3) on the LPC32xx.

Effectively, I would like to have a large receive FIFO with a > 0 byte interrupt trigger.  The documentation implies that a CTI / RDA interrupt is the correct mechanism, but I don't see an obvious way to configure that. 

Can someone clear up my confusion?

Thanks in advance,
Brian

Someone reported on another forum that they were getting the behavior I was looking for. Setting FCR register to zero seems to produce the right behavior.

Consider this issue dead.
