Explanation
1. Use this instruction with the high-speed counter numbers HC200 and above. The lower bound of S
than the upper bound of S
2. If S specifies a software counter and the specified counter changes by increasing or decreasing by 1 in value, the

DHSZ instruction makes the comparison immediately. The comparison condition and output state are shown in the
following table.
