UART0 Baudrate setting ARM

Hi

We are using Philips LPC2138 ARM Controller in our proto board with 10 MHz external Crystal.

We tried to make use of UART0 with baudrate 2400. For that, the code is:

#define UART_CLK        (10000000UL)    //10MHz Crystal

const unsigned char ABC[26]=
{'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};

void uart0Init(void)
{
        baud_val = ( (UART_CLK / 2400) / 16UL);

        U0IER = 0X00;
        U0IIR = 0X01;
        U0SCR = 0X00;
        U0FCR = 0X00;
        U0LCR = 0X00;
        U0MCR = 0X00;
        U0LSR = 0X60;
        U0LCR = 0X80;
        U0DLL = 0X00;
        U0DLM = 0X00;
        U0LCR = 0X00;

        U0LCR = 0x83;/* 8-bit bata, 1 stop bit, parity none */

        U0DLL = (baud_val & 0xFF);
        U0DLM = (baud_val >> 8);

        U0LCR = 0X03;

        U0TER = 0X80;
}

void sendDataToUart0(const unsigned char i)
{
        while(!(U0LSR & 0x20));/* If The Transmitter Ready Flag Is Set */

        U0THR = i;      /* Data Is Loaded Into The Transmitting Register */
}

void delay(void)
{
        unsigned int i;
        unsigned char k;

        for(k=0;k<75;k++)
        {
                for(i=0;i<50000;i++);
        }
}

void main(void)
{
        unsigned char a=0;

        PCONP = 0X0000020A;     /* Power Control for Peripherals register */
                                /* PCTIM0 = 1, PCUART0 = 1, PCRTC = 1 */
        PINSEL0 |= 0X00000005;  /* Pin Function Select Register 0 */
                                /* Select TXD (UART0) & RXD (UART0) */
        uart0Init();

        while(1)
        {
                delay();
                sendDataToUart0(ABC[a]);
                a++;
                if(a == 25)
                        a = 0;
        }
}

The problem is the characters are being printed wrongly on serial com port.

Is there any missing in the above coding?

thanks in advance.
