Inclusive OR W with f

d
(W) .OR. (f)
Z
Inclusive OR the W register with
register 'f'. If 'd' is 0 the result is
placed in the W register. If 'd' is 1
the result is placed back in regis-
ter 'f'.
Move f

0
d
(f)
Z
The contents of register f are
moved to a destination dependant
upon the status of d. If d = 0, des-
tination 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.
Inclusive OR Literal with W
[ label ]
0
(W) .OR. k
Z
The contents of the W register are
OR’ed with the eight bit literal 'k'.
The result is placed in the W reg-
ister.
