Down
Load value
The counting operation starts with the current count value.
Upper
count limit
If, while counting upwards, the counter reaches the upper count limit and
another counting pulse is received, the counter value jumps to the lower count
limit. The counter continues counting starting at the lower count limit.
Lower
count limit
If, while counting downwards, the counter reaches the lower count limit and
another counting pulse is received, the counter value jumps to the load value.
The counter continues counting starting at the load value.
Internal enable
The internal enable is not automatically reset. The counter remains active.
Note
The counting operation starts with the current count value. The user can preset this
value to a defined value (
