The crossbars (referred to as X-BAR throughout this chapter) provide flexibility to connect device inputs, outputs, and internal resources in a variety of configurations.
The device contains a total of six X-BARs:
Each of the X-BARs is named according to where the X-BAR takes signals. For example, the Input X-BAR and CLB Input X-BAR bring external signals “in” to the device. The Output X-BAR and CLB Output X-BAR take internal signals “out” of the device to a GPIO. The CLB X-BAR and ePWM X-BAR take signals to the CLB and ePWM modules, respectively.
