SUBWF

Subtract W from f

Syntax:

[ label ] SUBWF f,d

Operands:

f 127

 [0,1]

Operation:

(f) - (W)

destination)

Status Affected: C, DC, Z

Description:

Subtract (2’s complement method)

W register from register ‘f’. If ‘d’ is

‘0’, the result is stored in the W

stored back in register ‘f’.

SWAPF

Swap Nibbles in f

Syntax:

[ label ] SWAPF f,d

Operands:

 f  127

 [0,1]

Operation:

(f<3:0>)

 (destination<7:4>),

(f<7:4>)

 (destination<3:0>)

Status Affected:

None

Description:

The upper and lower nibbles of

‘0’, the result is placed in the W

placed in register ‘f’.

XORLW

Exclusive OR literal with W

Syntax:

[ label ] XORLW k

Operands:

k 255

Operation:

(W) .XOR. k

W)

Status Affected:

Description:

The contents of the W register

are XOR’ed with the 8-bit

literal ‘k’. The result is placed in

the W register.

C = 0

 f

C = 1

 f

DC = 0

W<3:0>

 f<3:0>

DC = 1

W<3:0>

 f<3:0>

XORWF

Exclusive OR W with f

Syntax:

[ label ] XORWF

f,d

Operands:

 f  127

 [0,1]

Operation:

(W) .XOR. (f)

destination)

Status Affected:

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’.
