5Fh
Subtract W and Carry from f
SUBWFC f, d
0 ≤ f ≤ FFh
d ∈ [0,1]
[Destination] ← [f] – [W] –C
C, DC, Z
Subtract the content of the W
register from [f]. If d is 0, the result
is stored in the W register. If d is
1, the result is stored back in [f].

XORLW
0 ≤ k ≤ FFh
[W] ← [W] XOR k
Z
Exclusive OR the content of the
W register and the eight-bit literal
"k". The result is stored in the W
register.
