INTERFACING THE ADS1606 TO THE
TMS320C6000
APPLICATIONS INFORMATION
INTERFACING THE ADS1605 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.
Figure 28 illustrates how to directly connect the ADS1605
to the TMS320C6000 DSP. The processor controls
reading using output ARE. The ADS1605 is selected 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.
