i am trying to dump some data onto the serial port.(uart 0)
i have configured all the registers mentioned in the data sheet.
still there is not a single byte of data on the serial port
the reg values that i have configured b4 writing to UART0_THR are

UART0_FCR |= 0X07; //fifo

UART0_LCR = 0X83; //line control reg - 8data bits, no parity,1stop bit

UART0_IER = 0X05;

UART0_DLL = 0X41; // for a baud of 9600
UART0_DLM = 0X00;
GPIO_IODIR |= 0xfffffff0;
GPIO_IOCLR |= 0xff00;

PCB_PINSEL0 |= 0x5; /*select 0.0 as txd of uart0

PCB_PINSEL0 &= 0xfffffff5;
