In1 is the input value. In2 and In3 specify the range that you want to
use for the maximum and minimum values for In1. In4 and In5
represent a double word that corresponds to the output value that you
want to use when In1 is equal to In2. In4 is the high word and In5 is
the low word. Likewise, In6 and In7 represent a double word that
corresponds to the output value that you want to use when In1 is equal
to In3. Therefore, it does not matter which value, In2 or In3, you use
for either the maximum or minimum. The following are some
examples.
The output is also specified as a double word, with the high word in
Function Output 1 and the low word in Function Output 2.

In2 represents the maximum input value, and
In3 represents the minimum input value.
In2 represents the minimum input value, and
In3 represents the maximum input value.
In2 represents the maximum input value, and
In3 represents the minimum input value.
Notice that the In4, In5 combination is smaller
than the In6, In7 combination. This is valid,
and if In1 is equal to In2, the output will still be
In4, In5.
