The positive edge of this command enables data streaming to the output. It also enables
clock, data sync, and frame sync outputs.
The positive edge of this command disables data streaming to the output. It also
disables clock, data sync, and frame sync outputs.

The signal enables the insertion of the frame number at the beginning of each frame. If
disabled, only the ADC data is streamed to the output.
This signal enables the output of the time sync pulses at all times when streaming is

enabled by the STRMEN command. Otherwise, the time sync pulses are available only
when data streaming is active at the output, for example, in the time intervals bound by
the STRMSTART and STRMSTOP commands.
This control signal enables the sync pulses at the DATASYNC output. Each pulse is
