Description:
The contents of the W register are
OR’ed with the eight-bit literal ‘k’.
The result is placed in the W
register.
Description:
The contents of register ‘f’ is
moved to destination ‘d’. If ‘d’ is ‘0’,
destination is the W register. If ‘d’
is ‘1’, the destination is file
register ‘f’. ‘d’ is ‘1’ is useful to test
a file register since Status flag Z is
affected.

Description:
The eight-bit literal ‘k’ is loaded
into the W register.
Description:
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
