(W) .OR. (f) → (W)
Z
00 0100 dfff ffff
Inclusive OR the W register to register
'f'. If 'd' is 0 the result is placed in the
W register. If 'd' is 1 the result is
placed back in register 'f'.

The eight bit literal 'k' is loaded into W
register. The don’t cares will assem-
ble as 0’s.

Move f
[ label ] MOVF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(f) → (dest)
Z
00 1000 dfff ffff
The contents of register f is moved to
destination 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.
