UART3 MCP2378

hi all , I am trying to configure the UART 3 of MCP2378 for the baud rate 115200.i successfully configured UART0 for the same baud rate .but when i tried it with UART 3 i get some junk values probably due to some baud rate miss match
following is the code used for initialization.

void UARTInit(u8 ucPortNo,u16 ucBaudrate)
{ UART_BaudRateConfig(ucPortNo,ucBaudrate);

switch(ucPortNo)
{

case 0: PINSEL0 =0x00000050; U0FCR =0x07; /* Enable and reset TX and RX FIFO.*/ break;

case 1: PINSEL0 |=0x40000000; //original PIN configuration PINSEL1 |=0x00000001; U1FCR =0x07; /* Enable and reset TX and RX FIFO.*/ break;

case 2: PCONP |=0x01000000; PINSEL0 |=0x00500000;//selecting thefunction for the pins

// PINSEL4 |= 0x000A0000; U2FCR =0x07; /* Enable and reset TX and RX FIFO.*/ break;

case 3: PCONP |=0x02000000; PINSEL9 |=0x0f000000;//selecting the function for the pin // PINSEL1 |= 0x003E0000; U3FCR =0x07; /* Enable and reset TX and RX FIFO.*/

break;
} }

UART_BaudRateConfig(u8 PortNo,u16 Baudrate)
{ u16 DIV;
switch(PortNo)
{ case 0: U0LCR =0x83;
// DIV=((Fpclk/16)/Baudrate);
// U0DLM = (DIV/256);
// U0DLL = (DIV%256); U0DLM =0x0; U0DLL =8;//0xa+;75 /* 38793 =0x1d */ U0FDR=0x92; U0LCR=0x03; break;

case 1:U1LCR =0x83;
// DIV=((Fpclk/16)/Baudrate); U1DLM =DIV / 256; U1DLL =DIV % 256; U1LCR=0x03; break;

case 2:U2LCR =0x83; U2TER =0x80;
// DIV=((Fpclk/16)/Baudrate);
// U2DLM =DIV / 256;
// U2DLL =DIV % 256; U2DLM =0x0; U2DLL =8; U2FDR=0x92; U2LCR =0x03; break;

case 3:U3LCR =0x83;

// DIV=((Fpclk/16)/Baudrate);
// U3DLM =DIV / 256;
// U3DLL =DIV % 256; U3DLM =0x0; U3DLL =8;//0xa+;75 /* 38793 =0x1d */ U3FDR=0x92; U3LCR=0x03; U3TER =0x80; break;
} }

here I directly configured the UART for 115200.I am using 24mhz main clock.
