5.8.3 Upper/Lower Limit (LIMIT)
( 1 ) Operation
The LIMIT instruction controls the output value so that it does not exceed the specified upper and lower limits for the
input value.
As shown in the following figure, if the input value is within the upper and lower limits, the input value is output unal-
tered.
The upper limit is output when the input value is greater than upper limit. The lower limit is output when the input
value is less than the lower limit.
( 2 ) Format
∗ C and # registers cannot be used.
Always set the lower limit to a value that is less than or equal to the upper limit.
d
If Lower limit ≤ Input value ≤ Upper value
Output value = Input value
c
If Input value > Upper limit
Output value = Upper limit
e
