Trigger Present (NB-IoT)

Default: Disabled

When Trigger Present is enabled (selected), the demodulator expects a trigger to start signal capture.

When selected, minimum capture for downlink is ~1 frame if Sync Type = NPSS or ~2 frames if Sync Type = NRS. Trigger is expected to indicate a two-frame boundary.

For uplink, the trigger is expected to be a burst trigger which starts at beginning of a burst (not the beginning of a frame).
