LPC3250 UART TRIGGER HELP

eswar g

Hi I have a problem on UART.I'm trying to receive the data using trigger levels. But from the first byte interrupt coming. As per the datasheet the interrupt has to come after reaching the trigger level only. But i'm getting interrupt for single character.

here i am attaching the configuration. Please help me.

      U6LCR=0x83;//DLAB enable,odd parity,disble break transmission,1 stop bit,8 bit character length
U6CLK =0x00000101;                      //x=1,y=1..115200
U6DLL=0x07;                             //115200 baud rate
U6DLM=0x00;
U6LCR=0x03;     //DLAB Disable,odd parity,disble break transmission,1 stop bit,8 bit character length
U6IER           |=0x03;                         // Enable Uart6 Rx & Tx interrupt
U6FCR            =0x1F;


Thanks
eswar
