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.
