Operation:
(W) .OR. k → (W)
Z
k → (W)
Status Affected: None
The contents of the W register are
OR’ed with the eight bit literal 'k'. The
result is placed in the W register.
The eight bit literal 'k' is loaded into W
register. The don’t cares will assem-
ble as 0’s.

Description:
Move data from W register to reg-
ister ’f’.
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’.

Status Affected:
Description:
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.
