13.2 Instruction Descriptions
ADDLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Add literal and W
[ label ] ADDLW k
0 ⤠k ⤠255
(W) + k â (W)
C, DC, Z
The contents of the W register
are added to the eight-bit literal âkâ
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 â [0,1]
(W) + (f) â (destination)
C, DC, Z
Add the contents of the W register
with register âfâ. If âdâ is â0â, the
result is stored in the W register. If
âdâ is â1â, the result is stored back
in register âfâ.
ANDLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
AND literal with W
[ label ] ANDLW k
0 ⤠k ⤠255
(W) .AND. (k) â (W)
Z
The contents of W register are
ANDâed with the eight-bit literal
âkâ. 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 â [0,1]
(W) .AND. (f) â (destination)
Z
AND the W register with register
âfâ. If âdâ is â0â, the result is stored in
the W register. If âdâ is â1â, the
result is stored back in register âfâ.
PIC16F684
BCF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Bit Clear f
[ label ] BCF f,b
0 ⤠f ⤠127
0â¤bâ¤7
0 â (f<b>)
None
Bit âbâ in register âfâ is cleared.
BSF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Bit Set f
[ label ] BSF f,b
0 ⤠f ⤠127
0â¤bâ¤7
1 â (f<b>)
None
Bit âbâ in register âfâ is set.
BTFSC
Bit Test, Skip if Clear
Syntax:
Operands:
Operation:
Status Affected:
Description:
[ label ] BTFSC f,b
0 ⤠f ⤠127
0â¤bâ¤7
skip if (f<b>) = 0
None
If bit âbâ in register âfâ is â1â, the next
instruction is executed.
If bit âbâ, in register âfâ, is â0â, the
next instruction is discarded, and
a NOP is executed instead, making
this a 2-cycle instruction.
