18.2.2 Host Master Timing
When in Master mode, the DMN-8600 controls an external slave device
through use of an async master interface. The DMN-8600 master
interface supports 68K and SRAM data strobe modes with either a
self-paced or device-paced protocol. The master interface can also
multiplex address and data lines.
Unless otherwise noted, cycle type variations are independent of each
other and can be mixed and matched as the system designer sees fit.
This accounts for a total of nine possible variations, as shown in
through
and described in
