( 3 ) Programming Example
In the following programming example, four bits from the first bit address at MB00001E are shifted two bits to the left
when switch 1 (DB000000) turns ON.
The following figure illustrates the result when the above instructions are executed.
0 0 1 1 0 1
0 0 0 1 0 0
E F 0 1 2 …
1 1
