AD664
Simple AD664 to MC68000 Interface
Figure 28 shows an AD664 connected to an MC68000. In this
memory-mapped I/O scheme, the “left-justified” data is written
in one 12-bit input word. Four address bits are used to perform
the on-chip D/A selection as well as the various operating fea-
tures. The R/W signal controls the RD function and system
reset controls RST.

This scheme can be converted to write “right-justified’’ data by
connecting the data inputs to DATA bits D0 through D11
respectively. Other options include controlling the QS0, QS1
and QS2 pins with UDS and LDS to provide a way to write
8-bit input and read 8-bit output words.
