You are right Uwe. I missed it. It was right under my nose ;)
Thank you,

take a look at the User Manual, p.89. Not too bad an explanation. ;-)

The CTI essentially means that there are characters in the receive FIFO but
not enough to pass the threshold and there are no characters coming in.

Hi,
I am working with the UART1 of the LPC2106 using the UARTecho sample program
with the KickStart board from IAR. The UART keeps generating the character
time-out indicator interrupt. I have looked through all of the documentation
from Philips and I cannot find an explanation of what actually causes this
interrupt. Does it mean that a stop bit was not found in nine bit times from the
start bit? Does it mean that the receive FIFO overran? Is this lack of a clear
and concise explanation indicative of Philips documentation? I am new to the
LPC210x family, so please excuse my lack of understanding if the answer is
obvious. I have worked mostly with Motorola micros and there documentation seems
more concise.
