The DMAXBAR is further made up of unit XBARs and the architecture allows for two tier selection of any one of the DMA request sources. Except for the ePWM SOCA and SOCB, rest of the DMA sources are active low and before entering the XBAR, these are inverted to be active high.
The DMAXBAR configured by writing to the DMAXBAR[0-15].G[0-5].SEL registers. The Figure 7-382 shows all IP sources and destinations and Table 7-222 provides a comprehensive list of the destinations. For more information on configuration, see the CONTROLSS_DMAXBAR register definitions.
