Hello
My customer chosen ADS7040 first time. ( ES coming soon )
This is the question about SDO read from customer's DSP( C6745).
~~~~~~~~~~~
We see following description in the data sheet 8.3.4 Serial Interface.
The first zero is launched on the SDO pin on the CS falling edge. Subsequent bits
(starting with another 0 followed by the conversion result) are launched on the
SDO pin on subsequent SCLK falling edges.
The SDO output remains low after 10 SCLKs.
A CS rising edge ends the frame and brings the serial data bus to 3-state.
~~~~~~~~~~~~~~~~~~~~~
Question : Is following sequence correct for reading data by DSP?
*DSP should read data by rising edge of SCLK.
*read data using a first rising edge of SCLK from CS=L ,to subsequent 9 rising edge ;total 10 rising edge.
I had attached ppt file for our understanding.
Best Regards
