PIC16F87XA
SWAPF
Swap Nibbles in f
Syntax:
[ label ] SWAPF f,d
Operands:
0 ⤠f ⤠127
d â [0,1]
Operation:
(f<3:0>) â (destination<7:4>),
(f<7:4>) â (destination<3:0>)
Status Affected: None
Description:
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.
XORLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR Literal with W
[ label ] XORLW k
0 ⤠k ⤠255
(W) .XOR. k â (W)
Z
The contents of the W register
are XORâed with the eight-bit
literal âkâ. 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 â [0,1]
(W) .XOR. (f) â (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.
