IBM PC* Interface
Figure 27 illustrates a simple interface between an IBM PC and
an AD664. The three least significant address bits are used to
select the Quad and DAC. The next two address bits are used
for LS and MS. In this scheme, a 12-bit input word requires
two load cycles, an 8-bit word and a 4-bit word. Another write

is required to transfer the word or words previously written to
the second rank. A 12-bit-wide word again requires at least two
read cycles; one for the 8 MSBs and four for the LSBs. The
page select signal produces a CS strobe for any address from
300H to 31FH.
