FX3/CX3 事件机制

1. CyU3PEvent glFxGpioAppEvent; //定义事件对象
2. retThrdCreate = CyU3PEventCreate(&glFxGpioAppEvent); //初始化事件对象
3. CyU3PEventSet(&glFxGpioAppEvent, CY_FX_GPIOAPP_GPIO_HIGH_EVENT, //设置信号
   CYU3P_EVENT_OR);
4. txApiRetStatus = CyU3PEventGet (&glFxGpioAppEvent, //检测信号
   (CY_FX_GPIOAPP_GPIO_HIGH_EVENT ),
   CYU3P_EVENT_OR_CLEAR, &eventFlag, CYU3P_WAIT_FOREVER);
