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’.

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.
