FTRigger (First TRigger) is used to generate a single TTLTRG output when
repeated triggers are being used to make multiple executions of the enabled
algorithms. The TTLTRG line will go low (asserted) at the first trigger event
and stay low through subsequent triggers until the trigger count (as set by
TRIG:COUNT) is exhausted. At this point the TTLTRG line will return to its
high state (de-asserted). This feature can be used to signal when the VT1422A
has started running its control algorithms.

Generated by the Algorithm Language function "interrupt()."
Generated on the First Trigger of a multiple "counted scan"
(set by TRIG:COUNT <trig_count>).
Generated by a Signal Conditioning Plug-on (SCP).
Do not use this when Sample-and-Hold SCPs are installed.
Generated every time a scan is triggered (see TRIG:SOUR
<trig_source>).
toggle TTLTRG line every time module is
triggered (use to trigger other VT1422As)
returns the current setting for the TTLTRG line source.
enter statement will return on of FTR,
SCP or TRIG
