SWAPF Swap Nibbles in f
Syntax: [ label ] SWAPF f,d
Operands: 0 ≤ f ≤ 127
d ∈ [0,1]
Operation: (f<3:0>) → (destination<7:4>),
(f<7:4>) → (destination<3:0>)
Status Affected: None
Description: 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’.
XORLW Exclusive OR Literal with W
Syntax: [label] XORLW k
Operands: 0 ≤ k ≤ 255
Operation: (W) .XOR. k → (W)
Status Affected: Z
Description: The contents of the W register
are XOR’ed with the eight-bit lit-
eral 'k'. The result is placed in
the W register.
XORWF Exclusive OR W with f
Syntax: [label] XORWF f,d
Operands: 0 ≤ f ≤ 127
d ∈ [0,1]
Operation: (W) .XOR. (f) → (destination)
Status Affected: Z
Description: 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'.
