Cp1 and Cp1+1 must be in the same data area, as must Cp2 and Cp2+1.

When the execution condition is OFF, CPSL(––) is not executed. When the
execution condition is ON, CPSL(––) compares the 32-bit (8-digit) signed binary
contents in Cp1+1, Cp1 and Cp2+1, Cp2 and outputs the result to the GR, EQ,
and LE flags in the SR area.

1. Refer to page 27 for details on 32-bit signed binary data.

2. Refer to 5-17-2 Compare – CMP(20) for details on saving comparison re-

sults.

Placing other instructions between CPSL(––) and the operation which accesses
the EQ, LE, and GR flags may change the status of these flags. Be sure to ac-
cess them before the desired status is changed.

EQ:
