8-BIT MICROPROCESSOR SYSTEMS
Figure 22 shows an interface circuit for the AD7845 to the
8085A 8-bit microprocessor. The software routine to load data
to the device is given in Table IV. Note that the transfer of the
12 bits of data requires two write operations. The first of these
loads the 4 MSBs into the 7475 latch. The second write opera-
tion loads the 8 LSBs plus the 4 MSBs (which are held by the
latch) into the DAC.

MICROPROCESSOR INTERFACING
16-BIT MICROPROCESSOR SYSTEMS
Figures 19, 20 and 21 show how the AD7845 interfaces to
three popular 16-bit microprocessor systems. These are the
MC68000, 8086 and the TM32010. The AD7845 is treated as
a memory-mapped peripheral to the processors. In each case, a
write instruction loads the AD7845 with the appropriate data.
The particular instructions used are as follows:
MC68000:
MOVE
8086:
MOV
TMS32010: OUT
