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

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
register ‘f’.

The eight bit literal ‘k’ is loaded
into W register. The “don’t
cares” will assemble as ‘0’s.

00
The contents of register ‘f’ is
moved to a destination
dependent 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.
