DMA 1 transfer Count.
The value of this register will be decremented by 1 after each transfer.
Low DMA 1 Destination Address.
These bits are mapped to A[15:0] during a DMA transfer.
The value of DDA [19:0] will be incremented or decremented by 2 or 1 after each
DMA transfer.

High DMA 1 Destination Address.
These bits are mapped to A[19:16] during a DMA transfer when the destination
address is in memory space or I/O space. If the destination address is in I/O
space (64Kbytes), these bits must be programmed to 0000b.
