0
≤
k
≤
255
k - (W)
→ (W)
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:

(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.
Status Affected: C, DC, Z
SUBWF
Syntax:

Description:
Subtract W from f
[

] SUBWF f,d
0
≤
f
≤
127
d
∈
[0,1]
(f) - (W)
→ (destination)
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'.

[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'.
Status Affected: C, DC, Z
SWAPF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Swap Nibbles in f

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'.
