5.2.3 HSZ Range Comparison
◆
Overview
Compare the present value of the counter with the comparison value. If the values are equal, immediately
reset the comparison output, 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]. In the instruction:
[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 C235–C255. As all counters involved are 32-bit counters, the
32-bit instruction DHSZ must be used.
[D] is the head address of three consecutive storage units for the comparison result: when it is Y0 to Y17
port, the result is immediately output; when it is a port with the number greater than Y20, the result is output
after the user program is scanned; for M, S, or SM variable, the result is immediately refreshed.

Note:
• The action principle of this instruction is similar to that of HSCS and HSCR instructions. The difference lies in that
two comparison values are used and the comparison output uses three consecutive address units. See the in-
struction for use of “5.2.2 HSCR Comparison Reset” on page 344.
• The HSZ instruction operates in interrupt mode. Only when corresponding inputs of the counter have count pulses,
comparison is carried out and corresponding outputs are refreshed.
