ZCPS/ZCPSL
Function
z ZCPS
ZCPS(117) compares the 16-bit signed binary data in CD with the range defined by LL and UL and
outputs the result to the Arithmetic Flags.
z ZCPSL
ZCPSL(118) compares the 32-bit signed binary data in CD+1, CD with the range defined by LL+1, LL
and UL+1, UL and outputs the result to the Arithmetic Flags.
Comparison Result and Flag Operation
Each flag shown below is ON when CD is on the bold lines or the filled circles.
Less Than Flag P_LT • ON if CD < LL.
• OFF in all other cases.
• ON if CD+1, CD < LL+1, LL.
• OFF in all other cases.
Less Than or Equal Flag P_LE • ON if CD ≤ UL.
• OFF in all other cases.
• ON if CD+1, CD ≤ UL+1, UL.
• OFF in all other cases.
