When EXT. TRIG is input while GATE is at High level,

data is enabled from the next scan.

Data collection timing by external one-shot trigger

(when enabled with falling edge)

The M-IN-START setting (T2) is ignored when this mode is selected.

But T1 stays enabled. Integration time depends on TX.
