Introduction

This example demonstrates the XINT feature in SysConfig by using it in conjunction with the input and output XBARs. The GPIO is toggled and connected to the input XBAR, while simultaneously triggering an external interrupt. The interrupt increments a counter which can be observed in the watch window. In addition to triggering an interrupt, the input signal is routed from the input XBAR to the output XBAR so that the output can be observed via oscilloscope or logic analyzer on a separate pin.

External Connections

• None

Watch variables

• counter - Number of interrupts generated
