SWAPF

Swap Nibbles in f

Syntax:

[ label ] SWAPF f,d

Operands:

 f  31

 [0,1]

Operation:

(f<3:0>)

 (dest<7:4>);

(f<7:4>)

 (dest<3:0>)

Status Affected: None

Description:

The upper and lower nibbles of

‘0’, the result is placed in W

placed in register ‘f’.

TRIS

Load TRIS Register

Syntax:

[ label ] TRIS

Operands:

f = 6

Operation:

(W)

 TRIS register f

Status Affected: None

Description:

TRIS register ‘f’ (f = 6, 7 or 8) is

loaded with the contents of the W

XORLW

Exclusive OR literal with W

Syntax:

[ label ]XORLW k

Operands:

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

XORWF

Exclusive OR W with f

Syntax:

[ label ] XORWF f,d

Operands:

 f  31

 [0,1]

Operation:

(W) .XOR. (f)

dest)

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

stored back in register ‘f’.
