DMACn
DMA Channel n. Each four bit field defines the logical connection between the DMA requestors and
that DMA channel. There are seven possible requesters (4 DMA Timers and 3 UARTs). Any request
can be routed to any of the DMA channels. Effectively, the DMAREQC provides a
software-controlled routing matrix of the 7 DMA request signals to the 4 channels of the DMA
module. DMAC3 controls DMA channel 3. DMAC2 controls DMA channel 2. DMAC1 controls DMA
channel 1. DMAC0 controls DMA channel 0.
