SUBLW
Subtract W from Literal
Syntax:
[ label ] SUBLW k
Operands:
0 ≤ k ≤ 255
Operation:
k - (W) → (W)
Status Affected: C, DC, Z
Description:
The W register is subtracted (2’s com-
plement method) from the eight bit lit-
eral 'k'. The result is placed in the W
register.
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.
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'.
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 regis-
ter 'f' are exchanged. If 'd' is 0, the
result is placed in 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'.
