Subtract W from f
[ label ] SUBWF f,d
0
d
(f) - (W)
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.

d
(f<3:0>)
(f<7:4>)
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’.

Exclusive OR W with f
[ label ] XORWF
0
d
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’.
Exclusive OR literal with W
[ label ] XORLW k
0
(W) .XOR. k
Z
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.
