IORWF
Inclusive OR W with f
Syntax:
[
label ]
IORWF
f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(W) .OR. (f)
→ (dest)
Status Affected:
Z
Encoding:
00
0100
dfff
ffff
Description:
Inclusive OR the W register with regis-
ter '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'.

IORWF
RESULT, 0
Before Instruction
RESULT =
0x13
W
=
0x91
After Instruction
RESULT =
0x13
W
=
0x93
Z=

MOVLW
Move Literal to W
Syntax:
[
label ]
MOVLW k
Operands:
0
≤ k ≤ 255
Operation:
k
→ (W)
Status Affected:
None
Encoding:

kkkk
Description:
The eight bit literal 'k' is loaded into W
register
. The don’t cares will assemble
as 0’s.

Example
MOVLW
0x5A
After Instruction
W
=
0x5A
MOVF
Move f
Syntax:
[

MOVF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f)

dfff
ffff
Description:
The contents of register f is moved to
a destination dependant upon the sta-
tus of d. If d = 0, destination is W reg-
ister. If d = 1, the destination is le
register f itself. d = 1 is useful to test a
le register since status ag Z is
affected.
