The EXT_IN terminal (terminal No.: A14) is a multi-function terminal for
which you can select a function.
The following two functions are available:
1. Clears comparison output:
Clears comparison result output (OK, NG, or JUDGE_OUT) at the falling
signal (active LOW) of the EXT_IN terminal. Note that output is not
cleared when the HOLD terminal (terminal No.: A15) is "L."
2. START & STOP:
Starts measurement at the falling signal (active LOW) of the EXT_IN
terminal and stops measurement at the rising of an input signal (active
HIGH). Measurement cannot start when the BUSY terminal is LOW.
For information on setting the multi-function terminal, see 7.5.2.
The maximum delay from the falling or rising edge until activation is 50 ms.
Activated when a edge is detected.
Input Signal
The EXT_IN terminal (A14) inputs a signal to LOW or HIGH level
according to the function selected.
