SWAPF
Swap Nibbles in f
Syntax:
[
label ] SWAPF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f<3:0>)
→ (dest<7:4>),
(f<7:4>)
→ (dest<3:0>)
Status Affected:
None
Encoding:
00
1110
dfff
ffff
Description:
The upper and lower nibbles of
register ’f’ are exchanged. If ’d’ is
0, the result is placed in W regis-
ter. If ’d’ is 1, the result is placed in
register ’f’.

TRIS
Load TRIS Register
Syntax:
[
label ] TRIS
f
Operands:
5
≤ f ≤ 7
Operation:
(W)
→ TRIS register f;
Status Affected:
None
Encoding:
00
0000
0110
0fff
Description:
The instruction is supported for
code compatibility with the
PIC16C5X products. Since TRIS
registers are readable and writ-
able, the user can directly address
them.
Words:
1
Cycles:
1
Example
To maintain upward compatibility
with future PIC12C67X products,
do not use this instruction.
XORLW
Exclusive OR Literal with W
Syntax:
[
label ]
XORLW k
Operands:
0
≤ k ≤ 255
Operation:
(W) .XOR. k
→ (W)
Status Affected:
Z
Encoding:
11
1010
kkkk
Description:
The contents of the W register
are XOR’ed with the eight bit lit-
eral 'k'. The result is placed in the
W register.
Words:
1
Cycles:
1
Example:
XORLW
0xAF
Before Instruction
W=
0xB5
After Instruction
W
=
0x1A
XORWF
Exclusive OR W with f
Syntax:
[
label ] XORWF
f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(W) .XOR. (f)
→ (dest)
Status Affected:
Z
Encoding:
00
0110
dfff
ffff
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 register 'f'.
Words:
1
