Description:
Words:
Cycles:
Example
Swap f
[ label SWAPF f,d
]
0 ≤ f ≤ 127
d ∈ [0,1]
(f<3:0>) → (dest<7:4>),
(f<7:4>) → (dest<3:0>)
None
00 1110 dfff ffff
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'.

SWAP F REG, 0
Before Instruction
REG1 = 0xA5
After Instruction
REG1 = 0xA5
W
= 0x5A
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.

Note:
To maintain upward compatibility with
future PIC16CXX products, do not use
this instruction.
XORLW

Example:
Exclusive OR Literal with W
[ label ] XORLW k
0 ≤ k ≤ 255
(W) .XOR. k → (W)
Z
11 1010 kkkk kkkk
The contents of the W register
are XOR’ed with the eight bit lit-
eral 'k'. The result is placed in
the W register.

Example
Exclusive OR W with f
[ label ] XORWF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(W) .XOR. (f) → (dest)
Z
00 0110 dfff ffff
Exclusive OR the contents of the
W register with register 'f'. If 'd' is
0 the result is stored in the W reg-
ister. If 'd' is 1 the result is stored
back in register 'f'.
