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
μ
s.
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.
