The following section describes the DMA Control registers.
The DMA Control register enables and control the DMA transfer (see
DMAxEN—DMA X enable. If this bit is written directly then normal mode is executed.
If this bit is read in from a descriptor then linked list mode is executed.
0 = DMA is disabled.
1 = DMA is enabled.
LOOP—LOOP mode
0 = Descriptor is modified when the buffer is closed.
1 = Descriptor is not modified when buffer is closed.
