GpioDataRegs.GPATOGGLE.bit.GPIO14 = 1不能工作



    EALLOW;

    GpioCtrlRegs.GPAMUX1.all = 0x00000510;

    GpioCtrlRegs.GPAMUX2.all = 0x05050000;

    GpioCtrlRegs.GPADIR.all = 0xfbf6ebf7; 

    GpioCtrlRegs.GPAQSEL1.all = 0x0000; 

    GpioCtrlRegs.GPAQSEL1.all = 0x0000; 

    GpioCtrlRegs.GPAPUD.all = 0x0009140b;

    GpioDataRegs.GPADAT.all = 0x00008000;

    EDIS;

请教一下,为何在同一个中断下GpioDataRegs.GPATOGGLE.bit.GPIO14 = 1无法使电平反转,而GpioDataRegs.GPATOGGLE.bit.GPIO30 = 1却能正常输出方波,GPIO14有什么特别的地方吗,是不是哪里需要配置啊。
