请教专家:
我需使用 MSP430F5528 的端口 P4.4,P4.5 做UART通信口.但是通信不成功. 下面是我的设置程序.
P4SEL |= BIT4 + BIT5;
UCA1CTL1 |= UCSWRST;
UCA1CTL1 |= UCSSEL_2; // SMCLK 6MHz
UCA1BR0 = 0x34; // 波特率115200
UCA1BR1 = 0x00;
UCA1MCTL = 0x40;UCA1CTL1 &= ~UCSWRST;
UCA1IFG = 0x00;
UCA1IE = 0x01;
UCA1IE |= UCRXIE; // 使能UCA1接收中断
请专家看看是否正确, 或需怎么改
