Lpc2000

  If you are having problems with interrupt mode operation of the
LPC uart, you might want to take a look at my code in the files
section on Yahoo. http://groups.yahoo.com/group/lpc2000/files/ 
and look for the descriptive title of UT040311A.zip

LPC210x datasheet :
"Key features: ... Multiple serial interfaces including two UARTs 
(16C550) ..."

I use interrupts to recieve bytes from Lpc210x UART.
The problem is, this UART generate only one RDA interrupt, when
last byte is recieved. There is no RLS interrupts - in means - UART
does not signal framing errors.
Earlier characters are lost with no error signalization...

From my experience I know, other UARTs (for exapmle in AVR or '550 
in PC) are ready to recieve next byte immediately after detecting 
first stop bit. Previous character is returned without framing error.

Has someone similar problem ?
