Configures the device to wait for a digital edge Reference Trigger to mark a reference point within the record.

You can use this trigger with the NI-TClk API.

Note The PXIe-5644/5645/5646 does not support the NI-TClk API.

Supported Devices: PXIe-5644/5645/5646, PXI-5661, PXIe-5663/5663E/5665/5667/5668, PXIe-5820/5830/5831/5832/5840/5841/5842/5860
