Notes on operand usage:
The operand D occupies three consecutive points

S1
: Compare value 1.
S2
: Compare value 2.
D
: Results of comparison.
 Compares the size of the content of operand
S1
and
S2
; the results of
comparison are expressed in
D
.
 Size comparison is performed algebraically. All data is compared in the form of
numerical binary values. Because this is a 16-bit command, when b15 is 1, this
indicates a negative number.
 When the designated device is Y0, it automatically occupies Y0, Y1 and Y2.
 When X10=On, the CMP command executes, and Y0, Y1 or Y2 will be On. When
X10=Off, the CMP command will not execute, and the state of Y0, Y1 and Y2 will
remain in the state prior to X10=Off.
 If ≥, ≤, or ≠ results are needed, they can be obtained via series/parallel
connections of Y0–Y2.
 To clear results of comparison, use the RST or ZRST command.
