Description:
(W) .OR. k → (W)
Z
k → (W)
None
The contents of the W register are
ORed 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 assemble as ‘0’s.
IORWF
Inclusive OR W with f
MOVWF
Move W to f

Description:
Z
Move data from W register to
register ‘f’.
Inclusive OR the W register with
register ‘f’. If ‘d’ = 0, the result is
placed in the W register. If ‘d’ = 1,
the result is placed back in
register ‘f’.
MOVF
Move f

Operation:
(f) → (destination)
Status Affected: None
Description: No operation.
Status Affected:
Description:
Z
The contents of register ‘f’ are
moved to a destination dependant
upon the status of ‘d’. If ‘d’ = 0,
the destination is W register. If
‘d’ = 1, the destination is file regis-
ter ‘f’ itself. ‘d’ = 1is useful to test
a file register since status flag Z is
affected.
