GPIO10引脚的一个功能是ADCSOCBO，这个引脚是不用通过XBR-opuput设置直接输出adcsocbo信号吗？用示波器测试为高电平无信号，请TI的专家帮忙看看。

// Soc Generate
EPwm1Regs.ETSEL.bit.SOCBSEL = ET_CTR_PRD;
EPwm1Regs.ETSEL.bit.SOCBEN = 1;
EPwm1Regs.ETPS.bit.SOCBPRD = ET_1ST;

//init soc gpio10
EALLOW;
GpioCtrlRegs.GPAGMUX1.bit.GPIO10 = 0; // Configure GPIO10 as ADCSOCBO
GpioCtrlRegs.GPAMUX1.bit.GPIO10 = 3; // Configure GPIO10 as ADCSOCBO
EDIS;

    不是直接输出的，还是需要配置的。

    您需要设置ADCSOCOUTSELECT等，您可以参考一下下面的代码

    //ADCSOCBO
        TrigRegs.ADCSOCOUTSELECT.bit.PWM7SOCBEN = 1;

        GpioCtrlRegs.GPAMUX1.bit.GPIO10 = 3;
        GpioCtrlRegs.GPAGMUX1.bit.GPIO10 = 0;
        GpioCtrlRegs.GPADIR.bit.GPIO10 = dGPIO_DIR_OUT;
        GpioCtrlRegs.GPAPUD.bit.GPIO10 = dGPIO_NO_PULL_UP;

        //Outputbar 6
        OutputXbarRegs.OUTPUT6MUX0TO15CFG.bit.Mux15 = 0x01;
        OutputXbarRegs.OUTPUT6MUXENABLE.bit.Mux15 = 1;

        GpioCtrlRegs.GPAMUX1.bit.GPIO9 = 3;
        GpioCtrlRegs.GPAGMUX1.bit.GPIO9 = 0;
        GpioCtrlRegs.GPADIR.bit.GPIO9 = dGPIO_DIR_OUT;
        GpioCtrlRegs.GPAPUD.bit.GPIO9 = dGPIO_NO_PULL_UP;
