The DMA x-bar is further made up of unit x-bars, which allows 2 tier selection of any one of the DMA request sources. Except for the ePWM(s) SOCA and SOCB, rest of the DMA sources are active low and before entering the x-bar, these are inverted to be active high.
The DMA x-bar configured by way of the DMAXBar[31:0].G[6:0].SEL and DMAXBAR[6:0].GSEL registers. The available IP sources for each INPUTx is shown in DMA x-bar figure below
