SUBWF
Subtract W from f
Syntax:
[ label ] SUBWF f,d
Operands:
0 ≤ f ≤ 127
d ∈ [0,1]
Operation:
(f) - (W) → (destination)
Status Affected: C, DC, Z
Description:
Subtract (2’s complement method)
W register from 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.
C=0
C=1
DC = 0
DC = 1
W>f
W≤f
W<3:0> > f<3:0>
W<3:0> ≤ f<3:0>
XORLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR literal with W
[ label ] XORLW k
0 ≤ k ≤ 255
(W) .XOR. k → (W)
Z
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.
SWAPF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Swap Nibbles in f
[ label ] SWAPF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(f<3:0>) → (destination<7:4>),
(f<7:4>) → (destination<3:0>)
None
The upper and lower nibbles of
register ‘f’ are exchanged. If ‘d’ is
‘0’, the result is placed in the W
register. If ‘d’ is ‘1’, the result is
placed in register ‘f’.
XORWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR W with f
[ label ] XORWF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(W) .XOR. (f) → (destination)
Z
Exclusive OR 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’.
