This counter counts up and down between a maximum counter value and a minimum counter value.
The following table shows the allowed range for the maximum and minimum counter values.
If the counter value exceeds the maximum counter value, the Counter Overflow Flag turns ON. If the
counter falls below the minimum counter value, the Counter Underflow Flag turns ON.
You can preset or reset the Counter Overflow Flag and Counter Underflow Flag to clear them.
If the count value exceeds the maximum counter value or falls below the minimum counter value, the
counter value will stay fixed at the maximum and minimum counter value. However, counting continues
internally so the count value can be updated again if it falls back within the valid range.
