Description:
Inclusive OR the W register with regis-
ter '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'.

dfff
ffff
Description:
The contents of register f is moved to
a destination dependant upon the sta-
tus of d. If d = 0, destination is W reg-
ister. If d = 1, the destination is le
register f itself. d = 1 is useful to test a
le register since status ag Z is
affected.
