We also need to configure the interrupt correctly: edge triggered or level triggered and which edge or level? We configure the interrupt using this function:

void XGpioPs_SetIntrTypePin(XGpioPs *InstancePtr, int Pin, u8 IrqType);

Where the IrqType is defined by one of the five definitions within the xgpiops.h file:

#define XGPIOPS_IRQ_TYPE_EDGE_RISING 0      /**< Interrupt on Rising edge */
#define XGPIOPS_IRQ_TYPE_EDGE_FALLING 1   /**< Interrupt Falling edge */
#define XGPIOPS_IRQ_TYPE_EDGE_BOTH 2        /**< Interrupt on both edges */
#define XGPIOPS_IRQ_TYPE_LEVEL_HIGH 3        /**< Interrupt on high level */
#define XGPIOPS_IRQ_TYPE_LEVEL_LOW 4         /**< Interrupt on low level */
