INTERFACING THE AD558 TO MICROPROCESSOR
DATA BUSES
The AD558 is configured to act like a “write only” location in
memory that may be made to coincide with a read only memory
location or with a RAM location. The latter case allows data
previously written into the DAC to be read back later via the
RAM. Address decoding is partially complete for either ROM
or RAM. Figure 12 shows interfaces for three popular micropro-
cessor systems.
