6 BASIC INSTRUCTIONS
6.1 Comparison Operation Instructions
Outputting a band comparison result of 16-bit binary data
ZCP(P)(_U)
These instructions compare the band between the 16-bit binary data specified by lower limit value (s1) and the 16-bit binary
data specified by upper limit value (s2) with the 16-bit binary data in the device specified by comparison data (s3). According
to the comparison result (below, within zone, or above), (d), (d)+1, or (d)+2 is turned on.
