Control input IN1 (start)

External or internal 
(word, bit 03)

Control input IN2 (latch
signal)

External or internal 
(word n, bit 04)

Internal (actual) counter value

Current counter value     
(words n+7 and n+6)

 

Counting flag
(word n + 4, bit 00)

1, 2, 3... 1.

Counting starts from 0 on the rising edge of IN1.

2.

The current counter value is latched (frozen) on the rising edge of IN2
(latch signal) and latched value is maintained until the next IN2 or IN1
signal.

3.

The internal counter value continues to be incremented and decrem-
ented without being affected by the latch signal.

4.

Both the internal current counter values are reset to 0 on the next IN1
signal. No outputs are supported by the latch mode.
