CC430F5137 spi不通？

TI的工程师：

你好！我用的是cc430f5137，准备用UCB0做为硬件SPI直接连传感器，程序如下：

               P1OUT &= ~ BIT7;  //cs
                PMAPPWD = 0x02D52;
                P1MAP2 = PM_UCB0SOMI;                     // Map UCA0SOMI output to P2.2                P1MAP3 = PM_UCB0SIMO;                     // Map UCA0SIMO output to P2.0                P1MAP4 = PM_UCB0CLK;                      // Map UCA0CLK output to P2.4                PMAPPWD = 0;                  P1SEL |= BIT2 +BIT3 +BIT4;                //选择spiio
                P1DIR |= BIT3 +BIT4 ;                     //输出
                UCB0CTL1 |= UCSWRST;                      // **Put state machine in reset**
                UCB0CTL0 |= UCMST+UCSYNC+UCCKPL+UCMSB;//+UCCKPH;    // 3-pin, 8-bit SPI master
                UCB0CTL1 |= UCSSEL_1;                         //aclk                UCB0BR0  |=0x02;
                UCB0BR1  |=0x00;
               // UCA0MCTL |=0x4A;
                UCB0CTL1 &= ~UCSWRST;

while（1）

{

读数据

}

现在的问题是，spi都没通，帮忙看下spi设置有问题？还是？谢谢了
