I'm trying to work out a problem I'm having with a XR16C854 UART.  It's a dual mode quad UART.  The version that I have is forced to 16 (intel) mode all the time, so there isn't a question of me being on the wrong mode.

I've been having difficulty getting the UART to actually transmit or recieve data, but I *can* trace the connections through my circuit from one side to the other.

I can also write to, and read from registers in the UART.  As near as I can tell, that pretty well restricts the source of the problem right down into the UART itself.  What I expect is that I'm not properly initializing the UART, and  that all I really need to do is get that right.

I can even read the revision ID out of the UART, so I'm pretty sure that I've got the right device/I/O address etc.

Has anyone here experienced similar problems?

Thanks,
--Brendan
