SWAPF
Swap Nibbles in f
Syntax:
[ label ] SWAPF f,d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(f<3:0>) → (dest<7:4>);
(f<7:4>) → (dest<3:0>)
Status Affected: None
Encoding:
0011 10df 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’.
Words:
1
Cycles:
1
Example
SWAPF REG1, 0
Before Instruction
REG1 = 0xA5
After Instruction
REG1 = 0xA5
W
= 0X5A
TRIS
Load TRIS Register
Syntax:
[ label ] TRIS f
Operands:
f=6
Operation:
(W) → TRIS register f
Status Affected: None
Encoding:
0000 0000 0fff
Description:
TRIS register ’f’ (f = 6 or 7) is
loaded with the contents of the W
register
Words:
1
Cycles:
1
Example
TRIS PORTB
Before Instruction
W
= 0XA5
After Instruction
TRIS = 0XA5
XORLW
Exclusive OR literal with W
Syntax:
[label] XORLW k
Operands:
0 ≤ k ≤ 255
Operation:
(W) .XOR. k → (W)
Status Affected: Z
Encoding:
1111 kkkk 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 ≤ 31
d ∈ [0,1]
Operation:
(W) .XOR. (f) → (dest)
Status Affected: Z
Encoding:
0001 10df ffff
Description:
Exclusive OR the contents of the
W register with register 'f'. If 'd' is 0,
the result is stored in the W regis-
ter. If 'd' is 1, the result is stored
back in register 'f'.
Words:
1
Cycles:
1
Example
XORWF REG,1
Before Instruction
REG = 0xAF
W
= 0xB5
After Instruction
REG = 0x1A
W
= 0xB5
