DMA/WAIT Control Register (DCNTL)
DCNTL controls the insertion of Wait States into DMAC (and CPU)
accesses of memory or I/O Also, the DMA request mode for each DREQ
DREQ0 and DREQ1) input is defined as level or edge sense. DCNTL
also sets the DMA transfer mode for channel 1, which is limited to
memory to/from I/O transfers.
