The Output X-BAR has eight outputs which can be selected on the GPIO mux as OUTPUTXBARx. The ePWM X-BAR has eight outputs which are connected to the TRIPx inputs of the ePWM. The sources for both the Output X-BAR and ePWM X-BAR are shown in Figure 4-8. For details on the Output X-BAR and ePWM X-BAR, see the Crossbar (X-BAR) chapter of the TMS320F2837xD Dual-Core Microcontrollers Technical Reference Manual.
