Move f

d
(f)
Z
The contents of register ‘f’ is
moved to a destination dependent
upon the status of ‘d’. If ‘d’ = 0,
destination is W register. If ‘d’ = 1,
the destination is file register ‘f’
itself. ‘d’ = 1 is useful to test a file
register since status flag Z is
affected.

None
The eight bit literal ‘k’ is loaded
into W register. The “don’t cares”
will assemble as ‘0’s
