Hi.
I am using 9 DDS devices for making phase simulation signals. These chips work well according to writing of configuration register. I conformed already that RD# and Address Signal send to DDS well. But I can't see any toggle in data path. DDS is configured by FPGA Logic and data signals of 9 DDS are connected by one data bus followed data buffer to FPGA.
Is there any problom or specific condition to read back the register I configured?
