CPS/CPSL
The following table shows the status of the Arithmetic Flags after execution of CPS(114).
* A status of “---” indicates that the Flag may be ON or OFF.
The following table shows the status of the Arithmetic Flags after execution of CPSL(115)
.
* A status of “---” indicates that the Flag may be ON or OFF.
Function
CPS
CPS(114) compares the signed binary data in S
1
and S
2
and outputs the result to Arithmetic Flags (the
Greater Than, Greater Than or Equal, Equal, Less Than or Equal, Less Than, and Not Equal Flags) in
the Auxiliary Area.
CPSL
CPSL(115) compares the double signed binary data in S
1
+1, S
1
and S
2
+1, S
2
and outputs the result to
Arithmetic Flags (the Greater Than, Greater Than or Equal, Equal, Less Than or Equal, Less Than, and
Not Equal Flags) in the Auxiliary Area.
