8.2.1 Block Diagram
Figure 8-1 shows a device level block diagram of the DMA.
Figure 8-1. DMA Block Diagram
A The ePWM/HRPWM registers must be remapped to PF3 (through bit 0 of the MAPCNF register) before they can be
accessed by the DMA. The ePWM/HRPWM connection to DMA is not present in silicon revision 0.
