Output value Word/Double word
Explanation:
1. The negative deviation in S
1
or the positive deviation in S
2
is added to the input value in S
3
,
and the sum is stored in D.
3
is less than 0, the negative deviation in S
1
the input value in S
3
, and the sum is stored in D.
3
is larger than 0, the positive deviation in S
2
the input value in S
3
, and the sum is stored in D.
3
is equal to 0, the output value stored in D is 0.
