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