Figure 16. AD7248A to 68008 Interface
An interface circuit for connections to the 6502 or 6809 micro-
processors is shown in Figure 17. Once again, the AD7248A is
memory mapped and data is right justified. T he procedure for
writing data to the AD7248A is as outlined for the 8085A/8088.
For the 6502 microprocessor the
φ
2 clock is used to generate
the
WR
, while for the 6809 the E signal is used.
Figure 17. AD7248A to 6502/6809 Interface
Figure 18 shows a connection diagram between the AD7248A
and the 8051 microprocessor. T he AD7248A is port mapped in
this interface and is configured in the automatic transfer mode.
Data to be loaded to the input latch low byte is output to Port 1.
Output Line P3.0, which is connected to
CSLSB
of the
AD7248A, is pulsed to load data into the low byte of the input
latch. Pulsing the P3.1 line, after the high byte data has been set
up on Port 1, updates the output of the AD7248A. T he
WR
in-
put of the AD7248A can be hardwired low in this application
because spurious address strobes on
CSLSB
and
CSMSB
do not
occur.
