CCS/MSP430G2553: msp430

Sir,

Thank you for your reply 

This is my code to  receive the  transmitted data from terminal  to MSP430G2553 without interrupt  and  using URXIFG0 flag.But not setting the mentioned flag and not getting the expected output. I am trying to do without using interrupt.

#include "msp430g2553.h"

#define TXLED BIT0
#define RXLED BIT6
#define TXD BIT2
#define RXD BIT1

unsigned int URXIFG0;
unsigned int i;

int main(void)
{
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
DCOCTL = 0; // Select lowest DCOx and MODx settings
BCSCTL1 = CALBC1_1MHZ; // Set DCO
DCOCTL = CALDCO_1MHZ;
P1DIR = BIT0;
P1OUT = BIT0+BIT6;

P2DIR |= 0xFF; // All P2.x outputs
P2OUT &= 0x00; // All P2.x reset
P1SEL |= RXD + TXD ; // P1.1 = RXD, P1.2=TXD
P1SEL2 |= RXD + TXD ; // P1.1 = RXD, P1.2=TXD
P1DIR |= RXLED + TXLED;
P1OUT &= 0x00;
UCA0CTL1 |= UCSSEL_2; // SMCLK
UCA0BR0 = 0x08; // 1MHz 115200
UCA0BR1 = 0x00; // 1MHz 115200
UCA0MCTL = UCBRS2 + UCBRS0; // Modulation UCBRSx = 5
UCA0CTL1 &= ~UCSWRST; // **Initialize USCI state machine**

while(1)
{
if(URXIFG0==1)
{
UCA0TXBUF = UCA0RXBUF;

}


P1OUT^=BIT0;
}

}
