* 1 : +3.3V, 10KΩ pull-up Input voltage range –0.5V to 6.0V.
* 2 : +3.3V, 10KΩ pull-up When all the trigger factors occur it outputs L pulse of about 1m
second.
* 3 : +3.3V, 10KΩ pull-up When specied for a trigger action, it outputs L pulse of about 1m
second.

When a new trigger occurs while outputting the trigger pulse, it becomes HIGH
level 1m second after the last trigger occurred.
Chapter 7 Trigger Function
7.1 Trigger Function
By the trigger function the line monitor make a specic measurement
control action upon occurrence of a specific factor such as
communication error while measurement. You can measure the
response time by controlling timer/counter and can count how much
the specic event occurred. The function makes your analysis more
ecient.
