5.4.4 HSZ Range Comparison
◆
Overview
The present value of the counter is compared with the comparison value. If the values are equal, the
comparison output is immediately reset, independent of the scan duration.

Functions and actions:
Compare the present value of the counter [S] with the set comparison range [S1] to [S2], and immediately
output the comparison result to three units starting with [D].
[S1] is the lower limit of the comparison range (32 bits), and its value must be no greater than the value of
[S2], that is, [S1] ≤ [S2].
[S2] is the upper limit of the comparison range (32 bits), and its value must be no smaller than the value of
[S1], that is, [S1] ≤ [S2].
[S] variables must be high-speed counters C252–C254. As all counters involved are 32-bit counters, the
32-bit instruction DHSZ must be used.
