按key1,key0都有反应，但按wk_up后LED无反应，再按key0.key1也没反应，mini板被卡住了，另外从始至终XCOM上没有OK输出，求大神指教...

Soitgoes

void EXTI_IRQHandler(void)
{
        //delay_ms(10);//Ïû¶¶
        if(WK_UP==1)        //WK_UP°´¼ü
        {
                LED0=!LED0;
                LED1=!LED1;
        }
        EXTI->R=1<<0;  //&Ccedil;&aring;&sup3;&yacute;LINE0&Eacute;&Iuml;&micro;&Auml;&Ouml;&ETH;&para;&Iuml;±ê&Ouml;&frac34;&Icirc;&raquo;

这是中断服务函数

Soitgoes

void KEY_Init(void)
{
        RCC->APB2ENR|=1<<2;                //&Ecirc;&sup1;&Auml;&UumlORTA&Ecirc;±&Ouml;&Oacute;
        RCC->APB2ENR|=1<<4;                //&Ecirc;&sup1;&Auml;&UumlORTC&Ecirc;±&Ouml;&Oacute;
        //JTAG_Set(SWD_ENABLE);
        GPIOA->CRL&=0XFFFFFFF0;//PA0&Eacute;è&Ouml;&Atilde;&sup3;&Eacute;&Ecirc;&auml;&Egrave;&euml;
        GPIOA->CRL|=0X00000008;
        GPIOA->CRH&=0X0FFFFFFF;//PA15&Eacute;è&Ouml;&Atilde;&sup3;&Eacute;&Ecirc;&auml;&Egrave;&euml;
        GPIOA->CRH|=0x80000000;
        GPIOA->ODR|=1<<15;                //PA15&Eacute;&Iuml;&Agrave;&shy;&pound;&notA0&Auml;&not;&Egrave;&Iuml;&Iuml;&Acirc;&Agrave;&shy;
        GPIOC->CRL&=0XFF0FFFFF;//PC5&Eacute;è&Ouml;&Atilde;&sup3;&Eacute;&Ecirc;&auml;&Egrave;&euml;
        GPIOC->CRL|=0X00800000;
        GPIOC->ODR|=1<<5;                        //PC5&Eacute;&Iuml;&Agrave;&shy;
}
这是初始化IO口代码
