MSP430f149Ti官方示例-UART01

    //******************************************************************************
    //  MSP-FET430P140 Demo - USART0, UART 115200 Echo ISR, HF XTAL ACLK
    //
    //  Description: Echo a received character, RX ISR used. Normal mode is LPM0,
    //  USART0 RX interrupt triggers TX Echo.
    //  ACLK = MCLK = UCLK0 = LFXT1 = 8MHz
    //  Baud rate divider with 8Mhz XTAL = 8000000/115200 = 0069 (0045h)
    //  //* An external 8Mhz XTAL on XIN XOUT is required for ACLK *//
    //  //* Min Vcc required varies with MCLK frequency - refer to datasheet *//
