IORLW
Inclusive OR Literal with W
Syntax:
[
label ]
IORLW k
Operands:
0
≤ k ≤ 255
Operation:
(W) .OR. k
→ (W)
Status Affected:
Z
Description:
The contents of the W register is
OR’ed with the eight bit literal 'k'. The
result is placed in the W register
.
IORWF
Inclusive OR W with f
Syntax:
[
label ]
IORWF
f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(W) .OR. (f)
→ (destination)
Status Affected:
Z
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'.
MOVF
Move f
Syntax:
[
label ]
MOVF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f)
→ (destination)
Status Affected:
Z
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 file
register f itself. d = 1 is useful to test a
file register since status flag Z is
affected.
MOVLW
Move Literal to W
Syntax:
[
label ]
MOVLW k
Operands:
0
≤ k ≤ 255
Operation:
k
→ (W)
Status Affected:
None
Description:
The eight bit literal 'k' is loaded into W
register
. The don’t cares will assem-
ble as 0’s.
MOVWF
Move W to f
Syntax:
[
label ]
MOVWF
f
Operands:
0
≤ f ≤ 127
Operation:
(W)
→ (f)
Status Affected:
None
Description:
Move data from W register to register
'f'
.
NOP
No Operation
Syntax:
[
label ]
NOP
Operands:
None
Operation:
No operation
Status Affected:
None
Description:
No operation.
