R8C13 Uart1 Problem

         Hi all,

         I regulated uart register settings like down..

         #define _OUT 0xFF
         #define _IN  0x00

        init_uart1(void)

{

         pd0_0=1;            //tx    
         pd3_7=0;            //rx

         u1mr = 0x05;   
          
         u1c0 = 0x00;  
         u1c1 = 0x0F;  

         ucon = 0x27;

         u1brg = 0x6E;        ( I want 19200 bit rate) my clock frequency=16 Mhz
 
         s1tic = 5;
         s1ric = 6;

}

         but , I couldn't work.. what is problem ??

         I think , u1brg is error . How can I do u1brg register setting? Can you tell me exactly .

         Thanks..
