SWAPF Swap Nibbles in f
Syntax: [ label ] SWAPF f,d
Operands: 0
f 127
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 regis-
ter ‘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’.
TRIS Load TRIS Register with W
Syntax: [ label ] TRIS f
Operands: 5
f 7
Operation: (W)
TRIS register ‘f’
Status Affected: None
Description: Move data from W register to TRIS
register.
When ‘f’ = 5, TRISA is loaded.
When ‘f’ = 6, TRISB is loaded.
When ‘f’ = 7, TRISC is loaded.
XORLW Exclusive OR literal with W
Syntax: [ label ]XORLW k
Operands: 0
k 255
Operation: (W) .XOR. k
W)
Status Affected: Z
Description: The contents of the W register are
XOR’ed with the 8-bit literal ‘k’. The
result is placed in the W register.
XORWF Exclusive OR W with f
Syntax: [ label ] XORWF f,d
Operands: 0
f 127
d
[0,1]
Operation: (W) .XOR. (f)
destination)
Status Affected: Z
Description: 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 regis-
ter ‘f’.
