( 3 ) Programming Example
In the following programming example, four bytes of data are expanded and moved from the area that starts with the
first source register address at MW00010 to the area of words that starts with the first destination register address at
MW00020.
The BEXTD instruction is executed when switch 1 (DB000000) turns ON.
The following table illustrates how the byte data in the source area is expanded and moved into word data in the desti-
nation area.
