Inclusive OR Literal with W

IORLW k

0 ≤ k ≤ 255

(W) .OR. k → W

N, Z

0000 1001 kkkk kkkk

The contents of W are ORed with the

eight-bit literal ‘k’. The result is placed

in W.

Q1

Decode

Inclusive OR W with f

IORWF f {,d {,a}}

0 ≤ f ≤ 255

d ∈ [0,1]

a ∈ [0,1]

(W) .OR. (f) → dest

N, Z

0001 00da ffff ffff

Inclusive OR W with register ‘f’. If ‘d’ is

‘0’, the result is placed in W. If ‘d’ is ‘1’,

the result is placed back in register ‘f’

(default).

If ‘a’ is ‘0’, the Access Bank is selected.

If ‘a’ is ‘1’, the BSR is used to select the

GPR bank (default).

If ‘a’ is ‘0’ and the extended instruction

set is enabled, this instruction operates

in Indexed Literal Offset Addressing

mode whenever f ≤ 95 (5Fh). See

Section 25.2.3 “Byte-Oriented and

Bit-Oriented Instructions in Indexed

Literal Offset Mode” for details.
