Flags
Note In CS1D CPU Units for Duplex Systems, CS1 CPU Units, and CJ1 CPU Units, these are turned OFF.
z 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.
z 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
z 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.
z 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.
