AD9914 external control for sweep mode

I trying to control sweep mode in AD9914 evaluation board through external hand sake singal DROVER & DRCTL from controller, at the same time I disable DRCTL/DROVER driver through jumper in evaluation board. but the sweep is not happening.

is it right to give external digital signal DRCTL by sensing DROVER signal for DDS for sweep mode in evaluation board, otherwise it need to programme DDS through SPI or Parallel port and use external signal DRCTL and DROVER for sweep mode external control ?
