msp432p401r launchpad接到电脑上没有反应，但是之前接上去会提示安装驱动，可能是之前驱动安装过程错误导致，这种情况该怎么做，请教一下TI的老师们

    一般来说，安装了CCS之后，驱动是自动安装的。您也可以采用如下步骤

    参考 http://energia.nu/guide/guide_windows/

    1. Do not connect your MSP-EXP432P401R LaunchPad to your PC. If you already plugged it into your PC then unplug it before proceeding to step 2.
    2. Download the LaunchPad drivers for Windows: MSP-EXP432P401R XDS110 Driver Package
    3. Unzip and double click DPinst.exe for Windows 32bit or DPinst64.exe for Windows 64 bit.
    4. Follow the installer instructions.
    5. Connect your MSP-EXP432P401R LaunchPad to your PC. The MSP-EXP432P401R will be automatically recognized.

    msp432p401r launchpad的系统时钟怎么配置48MHz时钟为系统时钟？我是这样配置代码的

    void main(void)
    {

    WDTCTL = WDTPW | WDTHOLD; // Stop WDT


    PJSEL0 |= BIT2 | BIT3; // Configure PJ.2/3 for HFXT function
    PJSEL1 &= ~(BIT2 | BIT3);

    CSKEY = CSKEY_VAL; // Unlock CS module for register access
    CSCTL2 |= HFXT_EN | HFXTFREQ_6 | HFXTDRIVE;
    while(CSIFG & HFXTIFG)
    CSCLRIFG |= CLR_HFXTIFG;

    /* Select MCLK & HSMCLK = HFXT, no divider */
    CSCTL1 = CSCTL1 & ~(SELM_M | DIVM_M | SELS_M | DIVHS_M) | SELM__HFXTCLK | SELS__HFXTCLK;

    CSKEY = 0; // Lock CS module from unintended accesses
    P1DIR |= BIT0;
    P1OUT |= BIT0;
    while(1)
    {
    P1OUT ^= BIT0;
    }
    }

    P4.3引脚输出是48MHz，但是P1.0的LED的灯引脚点评切换的频率只有1M，为什么？按道理P1.0的切换频率也应该是48MHz的，请大神指教。现在等在回复
