DMA Controller
14.4
The registers of each channel are mapped into memory as shown in
The DMA control module registers determine the operation of the DMA controller module. This section
describes each of the internal registers and its bit assignment.
14.4.1
The routing control register (DMAroute) controls where the non-processor DMA request for the four
DMA channels is coming from.
