PIC16F688
SWAPF
Swap Nibbles in f
Syntax:
[ label ] SWAPF f,d
0 ≤ f ≤ 127
Operands:
d
[0,1]
Operation:
(f<3:0>) → (destination<7:4>),
(f<7:4>) → (destination<3:0>)
Status Affected: 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
Exclusive OR Literal with W
Syntax:
[ label ] XORLW k
0 ≤ k ≤ 255
Operands:
Operation:
Status Affected:
Description:
(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.
XORWF
Exclusive OR W with f
Syntax:
[ label ] XORWF f,d
0 ≤ f ≤ 127
Operands:
d
[0,1]
Operation:
(W) .XOR. (f) → (destination)
Status Affected:
Description:
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’.
