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

Description:
Bit Test f, Skip if Set
[ label ] BTFSS f,b
0
0
skip if (f<b>) = 1
If bit ‘b’ in register ‘f’ is ‘0’, the next
instruction is executed.
If bit ‘b’ is ‘1’, then the next instruction is
discarded and a NOP is executed instead,
making this a 2-cycle instruction.
Bit Test f, 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
2-cycle instruction.
Bit Clear f
[ label ] BCF

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