| MOVF | Move f |
| Form |
[label] MOVFf, d
 ( label is omitable, shows SPACE code ) |
| Operands |
f : Register file addesss ( 00(00h) to 127(7Fh) )
d : Destination select ( 0 or 1 ) |
| Operation |
It moves (copy) the contents of the f register.
d = 0 : store result in W
d = 1 : store result in f
