Move f
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) → (destination)
Z
The contents of register ‘f’ are
moved to a destination dependant
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.
Move Literal to W
[ label ]
0 ≤ k ≤ 255
k → (W)
None
The eight bit literal ‘k’ is loaded
into W register. The don’t cares
will assemble as 0’s.
Move W to f
[ label ]
0 ≤ f ≤ 127
(W) → (f)
None
Move data from W register to
register ‘f’.

None
The W register is loaded with the
eight bit literal ‘k’. The program
counter is loaded from the top of
the stack (the return address).
This is a two-cycle instruction.
