Figure 11-15. Shadow Region Registers
11.3.7.2 Channel Controller Regions
There are eight EDMA3 shadow regions (and associated memory maps). Associated with each shadow
region are a set of registers defining which channels and interrupt completion codes belong to that region.
These registers are user-programmed per region to assign ownership of the DMA/QDMA channels to a
region.
