SUBWF
Subtract W from f
Syntax:
[ label ] SUBWF f,d
Operands:
0 ï£ï f ï£ï 127
d ï [0,1]
Operation:
(f) - (W) ï®ï ï¨destination)
Status Affected: C, DC, Z
Description:
Subtract (2âs complement method)
W register from register âfâ. If âdâ is
â0â, the result is stored in the W
register. If âdâ is â1â, the result is
stored back in register âf.
C=0
C=1
DC = 0
DC = 1

W<3:0> ï¾ f<3:0>
W<3:0> ï£ f<3:0>
XORLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR literal with W
[ label ] XORLW k
0 ï£ï k ï£ï 255
(W) .XOR. k ï®ï ï¨W)
Z
The contents of the W register
are XORâed with the eight-bit
literal âkâ. The result is placed in
the W register.
SWAPF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Swap Nibbles in f
[ label ] SWAPF f,d
0 ï£ f ï£ 127
d ï [0,1]
(f<3:0>) ï® (destination<7:4>),
(f<7:4>) ï® (destination<3:0>)
None
The upper and lower nibbles of
register âfâ are exchanged. If âdâ is
â0â, the result is placed in the W
register. If âdâ is â1â, the result is
placed in register âfâ.
XORWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR W with f
[ label ] XORWF f,d
0 ï£ f ï£ 127
d ï [0,1]
(W) .XOR. (f) ï®ï ï¨destination)
Z
Exclusive OR the contents of the
W register with register âfâ. If âdâ is
â0â, the result is stored in the W
register. If âdâ is â1â, the result is
stored back in register âfâ.
