The contents of the W register are
OR’ed with the eight bit literal 'k'. The
result is placed in the W register.

the W register. If 'd' is 1 the result is
placed back in register 'f'.

Z
The contents of register f are moved
to a destination dependant upon the
status of 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.
