5-3-2. High-speed counter range

The counting range of high-speed counter is: -2147483648 ~ +2147483647. When the count value exceeds this
range, overflow or underflow occurs.
The overflow means that the count value jumps from +2147483647 to -2147483648 and continues counting.
When underflow occurs, the count value jumps from -2147483648 to +2147483647 and continues counting.
