同时配置了GPIO24-28四个端口为输入模式，其余3个端口均能够正常输入，但是GPIO24引脚输入低电平时，DSP程序不运行，且工作状态混乱，请问是什么原因？下面是初始化配置程序：
GPIO_setDirectionMode(24, GPIO_DIR_MODE_IN); GPIO_setDirectionMode(25, GPIO_DIR_MODE_IN); GPIO_setDirectionMode(26, GPIO_DIR_MODE_IN); GPIO_setDirectionMode(27, GPIO_DIR_MODE_IN); GPIO_setPadConfig(24,GPIO_PIN_TYPE_PULLUP); GPIO_setPadConfig(25,GPIO_PIN_TYPE_PULLUP); GPIO_setPadConfig(26,GPIO_PIN_TYPE_PULLUP); GPIO_setPadConfig(27,GPIO_PIN_TYPE_PULLUP); GPIO_setPinConfig(GPIO_24_GPIO24); GPIO_setPinConfig(GPIO_25_GPIO25); GPIO_setPinConfig(GPIO_26_GPIO26); GPIO_setPinConfig(GPIO_27_GPIO27);
你好，可能是触发了24IO的errorsts状态，可以使能上拉电阻然后再运行程序。
