UCA0 用了这个串口就不能用了

P2.7//UCA0CLK

P3.2//UCA0STE

P3.3/UCA0TXD/UCA0SIMO

P3.4/UCA0RXD/UCA0SOMI

c
#include <msp430.h>
#include "oled.h"
#include "bmp.h"
//            |             P3.4|<- Data In (UCA0SOMI)
//            |    F5       P3.3|-> Data Out (UCA0SIMO)   --D1(OLED)
//            |             P2.7|-> Serial Clock Out (UCA0CLK)  --D0(OLED)
//            |             P2.0|->RES(OLED) 任意指定一个引脚
//            |             P2.2|->DC(OLED)  任意指定一个引脚
//            |              GND|->CS(OLED)  直接接GND片选上OLED
int main(void)
{
    WDTCTL = WDTPW + WDTHOLD; /* Stop WDT */
    OLED_Init(); /* OLED初始化 */
    OLED_DrawBMP(0,0,128,64,BMP1);
    while (1)
    {
    }
}

速度太快了，一整张图一瞬间的事情。
