When the execution condition is OFF, CMP(028) is not executed. When the ex-
ecution condition is ON, CMP(028) compares constants and/or the contents of
specified words as unsigned 16-bit binary data and changes the status of com-
parison flags according to the results.
After CMP(028) execution, the A50005 (GR), A50006 (EQ), and A50007 (LE)
flags turn ON and OFF as shown in the following table.

When CIO 000000 is ON in the following example, the content of CIO 0011 and
CIO 0010 is compared with that of CIO 0009 and CIO 0008 as binary data.
• If the content of CIO 0011 and CIO 0010 is greater than that of CIO 0009 and
CIO 0008, then output CIO 002000 will turn ON.
