Data Control Instructions
Section 3-18
Flags
Precautions
If the upper limit is less than the lower limit, an error will occur and the Error
Flag will turn ON.
If the input data (S) is greater than the upper limit, the Greater Than Flag will
turn ON.
If the output word D is 0000 hex, the Equals Flag will turn ON.
If the input data (S) is less than the lower limit, the Less Than Flag will turn
ON.
If the status of the leftmost bit of the output word D is “1,” the Negative Flag
will turn ON.
Example
When CIO 000000 is ON, a bias of –100 will be applied to the value of
D00100 if that value is less than 0, and the resulting value will be stored in
D00300.
If the value of D00100 is 0, then 0000 hex will be stored in D00300.
If the value of D00100 is greater than 0, then a bias of +100 will be applied
and the resulting value will be stored in D00300.
