Notes on operand usage:
The operand D occupies three consecutive points

Compares the size of the content of operand

comparison are expressed in
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.
