Figure 11-61 shows VBLNK from Group 1 and ACTVID(2) from Group 2 being used. ACTVID is not toggling during Vertical Blanking. Set USE_ACTVID_HSYNC_N=’1’ and DISCRETE_BASIC_MODE=’1’. Since there are no line sync/clocking signals in the Vertical Blanking period, only Active Video lines will be sent to the Active Video output.
If DISCRETE_BASIC_MODE=’0’ is set, then the hardware will lock up as there is no way for it to determine a frame boundary.
