Instruction Descriptions
Add W and f
[label] ADDWF
0
d
(W) + (f)
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’.
AND W with f
[label] ANDWF
0
d
(W) .AND. (f)
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'.
(W) + k
(W) .AND. (k)
Add Literal and W
[label] ADDLW
0
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.
AND Literal with W
[label] ANDLW
0
Z
The contents of W register are
AND’ed with the eight bit literal
'k'. The result is placed in the W
register.

Bit Test, Skip if Clear
[label] BTFSC f,b
0
0
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 2T
Bit Test f, Skip if Set
[label] BTFSS f,b
0
0
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
2T
Bit Clear f
[label] BCF

0
0
None
Bit 'b' in register 'f' is cleared.
Bit Set f
[label] BSF
