Move literal to W
[ label ]
0 ≤ k ≤ 255
k → (W)
The eight-bit literal ‘k’ is loaded into
W register. The “don’t cares” will
assemble as ‘0’s.

Move f
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) → (dest)
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.
