PIC16F87X
SWAPF
Swap Nibbles in f
Syntax:
Operands:
Operation:
Status Affected:
[ label ] SWAPF f,d
0  f  127
d  [0,1]
(f<3:0>)  (destination<7:4>),
(f<7:4>)  (destination<3:0>)
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
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR Literal with W
[label] XORLW k
0 k 255
(W) .XOR. k W)
Z
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
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR W with f
[label] XORWF f,d
0  f  127
d  [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'.
