Detailed Description
Frame Sync
The DXP software defaults to Frame Sync. The Frame Sync output of the MMB0
connects to the SYNC input of the DAC88811. The DAC output changes to the
corresponding level when the DAC latch is updated via SDI. Ensure the shunt jumper
on W6 is covering pins 2-3 (default is 1-2) to use this feature.
