CCS/MSP430F5438A: Send multiple bytes in a given time

Tool/software: Code Composer Studio

Hi,

I am trying to create an easy program which sends 3 byte ('A', 'B' and 'C') every second. But the problem is that I just can obtain de first byte ('A'), the othe two do not appear. How can I solve this? 

This is my code:

#include <msp430.h>

unsigned char data [3]={'A','B','C'};


void uartSend (unsigned char *pucData, unsigned char ucLength)
{
  while(ucLength !=0)
  {
    // Wait for TX buffer to be ready for new data
    while(!(UCA1IFG & UCTXIFG));

    // Push data to TX buffer
    UCA0TXBUF = *pucData;

    // Update variables
    ucLength--;
    pucData++;
  }

  // Wait until the last byte is completely sent
  while(UCA0STAT & UCBUSY);

}


int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
  P1DIR |= 0x01;                            // P1.0 output
  TA1CCTL0 = CCIE;                          // CCR0 interrupt enabled
  TA1CCR0 = 32768-1;
  TA1CTL = TASSEL_1 + MC_1 + TACLR;         // ACLK, upmode, clear TAR


  //Configuración UART
     UCA0CTL1 |= UCSWRST;                      // **Put state machine in reset**
     UCA0CTL1 |= UCSSEL_2;                     // SMCLK
     UCA0BR0 = 6;                              // 1MHz 9600 (see User's Guide)
     UCA0BR1 = 0;                              // 1MHz 9600
     UCA0MCTL = UCBRS_0 + UCBRF_13 + UCOS16;   // Modln UCBRSx=0, UCBRFx=0,
                                               // over sampling
 	P3SEL = 0x30;                             // P3.4,5 = USCI_A0 TXD/RXD
     UCA0CTL1 &= ~UCSWRST;                     // **Initialize USCI state machine**

  __bis_SR_register(LPM3_bits + GIE);       // Enter LPM3, enable interrupts
  __no_operation();                         // For debugger
}

// Timer A0 interrupt service routine
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=TIMER1_A0_VECTOR
__interrupt void TIMER1_A0_ISR(void)
#elif defined(__GNUC__)
void __attribute__ ((interrupt(TIMER1_A0_VECTOR))) TIMER1_A0_ISR (void)
#else
#error Compiler not supported!
#endif
{
	 while (!(UCA0IFG&UCTXIFG)); // USCI_A0 TX buffer ready?
	  uartSend(data,3);

}

In the picture the data received through UART is shown.

Thanks in advance,
