Comparison Instructions Section 5-19
Example The following example shows the comparisons made and the results provided
for BCMP(68). Here, the comparison is made during each cycle when IR
00000 is ON.
5-19-4 DOUBLE COMPARE – CMPL(60)
Limitations Cp1 and Cp1+1 must be in the same data area.
Cp2 and Cp2+1 must be in the same data area.
Set the third operand to 000.
Description When the execution condition is OFF, CMPL(60) is not executed. When the
execution condition is ON, CMPL(60) joins the 4-digit hexadecimal content of
Cp1+1 with that of Cp1, and that of Cp2+1 with that of Cp2 to create two 8-
digit hexadecimal numbers, Cp+1,Cp1 and Cp2+1,Cp2. The two 8-digit num-
bers are then compared and the result is output to the GR, EQ, and LE flags
in the SR area.
Precautions Placing other instructions between CMPL(60) and the operation which
accesses the EQ, LE, and GR flags may change the status of these flags. Be
sure to access them before the desired status is changed.
