Move f
[ label ]
d ∈ [0,1]
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'.

0 ≤ k ≤ 255
k → (W);

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.
