24.2 Instruction Descriptions
ADDFSR
Syntax:
Operands:
Operation:
Status Affected:
Description:
Add Literal to FSRn
[ label ] ADDFSR FSRn, k
-32  k  31
n  [ 0, 1]
FSR(n) + k  FSR(n)
None
The signed 6-bit literal ‘k’ is added to
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.
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’.
ADDWFC
Syntax:
Operands:
Operation:
Status Affected:
Description:
ADD W and CARRY bit to f
[ label ] ADDWFC f {,d}
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’.
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’.
ASRF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Arithmetic Right Shift
[ label ] ASRF f {,d}
0  f  127
d [0,1]
(f<7>) dest<7>
(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’.
