Description
MOVB IN, OUT
MOVW IN, OUT
MOVD IN, OUT
MOVR IN, OUT
The Move Byte, Move Word, Move Double Word, and Move Real instructions move
a data value from a source (constant or memory location) IN to a new memory
location OUT, without changing the value stored in a source memory location.
Use the Move Double Word instruction to create a pointer. For more information,
refer to the section on pointers and indirect addressing (Page 70).
