The DMA Destination Address Register Channel 0
specifies the physical destination address for channel 0
transfers. The register contains 20 bits and can specify up
to 1024-KB memory addresses or up to 64-KB I/O
addresses. Channel 0 destination can be memory, I/O, or
memory mapped I/O. For I/O, the
identify the Request Handshake signal for channel 0.
