AD9102 output going to midrange after pattern period executed


We are evaluating the behavior of the AD9102 using the EVM.

What we are observing is that after each pattern period is executed, the DAC output goes to midrange. 

Is there a way to prevent this?

We are storing a waveform in SRAM and we are executing a single pattern period. We would like the output to stay and hold the last value in the pattern. (the value written in SRAM at address STOP_ADDR).

Best regards,
