Problem Using LoopBack mode with SPI

Other Parts Discussed in Thread: MSP430G2553

I am trying to verify that my SPI has been configured properly and that my receive interrupts are working. For some reason I can't get it to receive the byte that I send. I have enabled the loopback mode but it doesn't seem like it is actually receiving anything that I send. I am using an MSP430g2553

Here is my code: 

#include <msp430.h>				

void initSPI_USCIA(void);							//initializes SPI on USCIA0 for the sd card reader/writer
//void initI2C_USCIB(void);							//initializes I2C on USCIB0 for the ADC from ASI
void initLED(void);									//initializes led so we can toggle it
__interrupt void USCI0RX_ISR (void);

void main(void) {
	WDTCTL = WDTPW | WDTHOLD;							//Stop watchdog timer
	initLED();
	initSPI_USCIA();


	while (!(IFG2 & UCA0TXIFG)){
		//wait for ready to transmit
	}
	UCA0TXBUF = 0x11;									//writes to spi data register

	_BIS_SR(LPM4_bits + GIE); 							// Enter LPM4 w/interrupts enabled

}



void initSPI_USCIA(void){
	UCA0CTL1 |= UCSWRST; 							//set software reset to 1 so we can configure SPI

	UCA0STAT |= UCLISTEN;							//the launchpad listens to itself (use for testing)
	UCA0CTL0 |= UCCKPH + UCMSB + UCMST + UCSYNC;	//clkphase,clkpolarity,MSBfirst,8-bit,master mode, 3-pin, synchronous SPI
	UCA0CTL1 |= UCSSEL_2;                   		//choose SMCLK as our clock. SMCLK is 1.1 MHz. We divise it with the baud register
	UCA0BR0 |= 0x02;                       			//Baud rate is 1.1MHZ/(2+1) = 366 KHz
	UCA0BR1 = 0;                            		//upper byte of br register. set to zero
	UCA0MCTL = 0;                           		//No modulation

	P1SEL |= (BIT1 | BIT2 | BIT4);			//configures pins for three pin SPI. MISO P1.1, MOSI P1.2, CLK P1.4
	P1SEL2 |= (BIT1 | BIT2 | BIT4);			//configures pins for their peripheral setting

	UCA0CTL1 &= !UCSWRST;                   //enables the SPI to work

	IE2 |= UCA0RXIE;                        // Enable USCI0 RX interrupt
}

void initLED(void){
		 P1DIR |= BIT0;                     //sets red led to output and turns it on
		 P1OUT &= !BIT0;				    //turn red led off
}

#pragma vector = USCIAB0RX_VECTOR
__interrupt void USCI0RX_ISR (void){
	if(UCA0RXBUF == 0x11)
	{
		P1OUT = 0x01;				    //turn red led on
	}


}
