( 3 ) Programming Example
In the following programming example, four bits of data are moved from the area that starts with the first source bit
address at MB000010 to the area that starts with the first destination bit address at MB000020.
The MOVB instruction is executed when switch 1 (DB000000) turns ON.
The following table illustrates how the data in the source area is moved to the destination area.
