Values in parentheses are for counter 2.
1,2,3...
1.
The counter resets the count value at the rising edge of control input IN1.
2.
The counter starts counting at the rising edge of control input IN2.
3.
The counter stops counting at the falling edge of control input IN2 and the
count value is kept on hold until the counter restarts.
4.
The counter is in operation again at the rising edge of control input IN2,
starting from the count value kept on hold.
Sampling Mode
Values in parentheses are for counter 2.
1,2,3...
1.
The sampling time must be set in word n+1 before the counter starts count-
ing.
The sampling time must be set by turning word n bit 01 or 02 ON.
2.
The counter resets the count value and starts counting at the rising edge
of control input IN1. The counter stops counting after the sampling time
elapses.
The count value is kept on hold until the counter restarts.
3.
If the new sampling time is set and word n bit 01 or 02 is turned ON while
the counter is counting, the new sampling time will be enabled after the
counter stops counting.
