APPLICATIONS INFORMATION
INTERFACING THE ADS1605 TO THE
TMS320C6000
Figure 28 illustrates how to directly connect the
ADS1605 to the TMS320C6000 DSP. The processor
controls reading using output ARE. The ADS1605 is se-
lected using the DSP control output, CE2. The
ADS1605 16-bit data output bus is directly connected
to the TMS320C6000 data bus. The data ready output
from the ADS1605, DRDY, drives interrupt EXT_INT7
on the TMS320C6000.

INTERFACING THE ADS1606 TO THE
TMS320C6000
Figure 29 illustrates how to directly connect the
ADS1606 to the TMS320C6000 DSP. The processor
controls reading using output ARE. The ADS1606 is
permanently selected by grounding the CS pin. The
ADS1606 16-bit data output bus is directly connected
to the TMS320C6000 data bus. The data ready output
from the ADS1606, DRDY, drives interrupt EXT_INT7
on the TMS320C6000.
