A trigger signal may be input from an external device.
The trigger is activated when the EXT_TRIG terminal (terminal No.: A7)
detects a falling signal (active LOW).
The maximum delay from the falling edge until activation is 100 μs.
When STORAGE terminal begins to output LOW signal, triggering is
acceptable. (See 8.5.7)
Input Signal
The EXT_TRIG terminal (A7) must be shorted with EXT_COM (A3), or a
low-level signal must be input to these terminals.
The trigger is activated at the falling edge.
Input signals of up to 1 KHz are available to activate the trigger.
