AD9102 Trigger and UPDATE bit (0x1D)

Hello everybody,

tried to send the registers which are in the example6.regval to FPGA, after that, I sent 0x01 to register 0x1D and then set Trigger high and low. But I have no Sine wave from DAC.

1- Should I repeat UPDATE bit (0x1D) for the trigger as well?

2- Is any specific time for trigger needed?

3- Is any specific time for UPDATE bit (0x1D) needed?

4- For Sine wave from DDS, should I write some data into the RAM? 

5- How can I read the sent data (from FPGA) through AD9102 software?
