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 regis-
ter 'f' are exchanged. If 'd' is 0 the
result is placed in W register. 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 prod-
ucts. Since TRIS registers are read-
able and writable, the user can directly
address them.
Words:
1
Cycles:
1
Example
To maintain upward compatibility
with future PIC16CXX 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 literal 'k'.
The result is placed in the W regis-
ter.
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:
