d
(W) .OR. (f)
Z
Inclusive OR the W register with
register ‘f’. If ‘d’ = 0, the result is
placed in the W register. If ‘d’ = 1,
the result is placed back in
register ‘f’.
Move f

d
(f)
Z
The contents of register ‘f’ are
moved to a destination dependant
upon the status of ‘d’. If ‘d’ = 0,
the destination is W register. If
‘d’ = 1, the destination is file regis-
ter ‘f’ itself. ‘d’ = 1 is useful to test
a file register since status flag Z is
affected.
Inclusive OR Literal with W

0
(W) .OR. k
Z
The contents of the W register are
ORed with the eight-bit literal ‘k’.
The result is placed in the W
register.
