13.1 Instruction Descriptions
ADDLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Add Literal and W
[label] ADDLW k
0 ≤ k ≤ 255
(W) + k → (W)
C, DC, Z
The contents of the W register
are added to the eight bit literal ’k’
and the result is placed in the W
register.
ADDWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Add W and f
[label] ADDWF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(W) + (f) → (destination)
C, DC, Z
Add the contents of the W register
with register ’f’. If ’d’ is 0, the result
is stored in the W register. If ’d’ is
1, the result is stored back in
register ’f’.
ANDLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
AND Literal with W
[label] ANDLW k
0 ≤ k ≤ 255
(W) .AND. (k) → (W)
Z
The contents of W register are
AND’ed with the eight bit literal
'k'. The result is placed in the W
register.
ANDWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
AND W with f
[label] ANDWF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(W) .AND. (f) → (destination)
Z
AND the W register with register
'f'. If 'd' is 0, the result is stored in
the W register. If 'd' is 1, the result
is stored back in register 'f'.

BCF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Bit Clear f
[label] BCF f,b
0 ≤ f ≤ 127
0≤b≤7
0 → (f<b>)
None
Bit 'b' in register 'f' is cleared.
BSF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Bit Set f
[label] BSF f,b
0 ≤ f ≤ 127
0≤b≤7
1 → (f<b>)
None
Bit 'b' in register 'f' is set.
BTFSS
Bit Test f, Skip if Set
Syntax:
Operands:
Operation:
Status Affected:
Description:
[label] BTFSS f,b
0 ≤ f ≤ 127
0≤b<7
skip if (f<b>) = 1
None
If bit 'b' in register 'f' is '0', the next
instruction is executed.
If bit 'b' is '1', then the next instruc-
tion is discarded and a NOP is
executed instead, making this a
2TCY instruction.
BTFSC
Bit Test, Skip if Clear
Syntax:
Operands:
Operation:
Status Affected:
Description:
[label] BTFSC f,b
0 ≤ f ≤ 127
0≤b≤7
skip if (f<b>) = 0
None
If bit 'b' in register 'f' is '1', the next
instruction is executed.
If bit 'b', in register 'f', is '0', the
next instruction is discarded, and
a NOP is executed instead, making
this a 2TCY instruction.
