Instruction Descriptions
Add W and f
[ label ] ADDWF
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’.
ADD W and CARRY bit to f
[ label ] ADDWFC
0  f  127
d [0,1]
(W) + (f) + (C)  dest
C, DC, Z
Add W, the Carry flag and data mem-
ory location ‘f’. If ‘d’ is ‘0’, the result is
placed in W. If ‘d’ is ‘1’, the result is
placed in data memory location ‘f’.
[ label ] ADDFSR FSRn, k
n  [ 0, 1]
FSR(n) + k  FSR(n)
the contents of the FSRnH:FSRnL
register pair.
FSRn is limited to the range
0000h-FFFFh. Moving beyond these
bounds will cause the FSR to
wrap-around.
[ label ] ADDLW
0  k  255
(W) + k  (W)
The contents of the W register are
added to the eight-bit literal ‘k’ and the
result is placed in the W register.
Add Literal to FSRn
-32  k  31
None
The signed 6-bit literal ‘k’ is added to

AND W with f
[ label ] ANDWF
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’.
AND literal with W
[ label ] ANDLW
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.

(f<7:1>)  dest<6:0>,
(f<0>)  C,
C, Z
The contents of register ‘f’ are shifted
one bit to the right through the Carry
flag. The MSb remains unchanged. If
‘d’ is ‘0’, the result is placed in W. If ‘d’
is ‘1’, the result is stored back in reg-
ister ‘f’.
