moved to St + 2, etc., and the content of E is lost.

5-13 Data Movement
This section describes the instructions used for moving data between differ-
ent addresses in data areas. These movements can be programmed within
the same data area or between different data areas. Data movement is es-
sential for utilizing all of the data areas of the PC. All of these instructions
change only the content of the words to which data is being moved, i.e., the
content of source words is the same before and after execution of any of the
move instructions.
