( 3 ) Programming Example
In the following programming example, the data specified as 8 bits wide from the first bit address at MB000000 is
rotated two bits to the left.
The ROTL instruction is executed when switch 1 (DB000000) turns ON.
The following figure shows the operation when MW00000 is 12,345 (3039 hex).
