SUBWF

Subtract W from f

Syntax:

[ label ] SUBWF f,d

Operands:

0 f 127

d  [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

register. If ‘d’ is ‘1’, the result is

stored back in register ‘f’.

C=0

C=1

DC = 0

DC = 1

Wf

Wf

W<3:0>  f<3:0>

W<3:0>  f<3:0>

XORWF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Exclusive OR W with f

[ label ] XORWF f,d

0  f  127

d  [0,1]

(W) .XOR. (f) destination)

Z

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’.

SWAPF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Swap Nibbles in f

[ label ] SWAPF f,d

0  f  127

d  [0,1]

(f<3:0>)  (destination<7:4>),

(f<7:4>)  (destination<3:0>)

None

The upper and lower nibbles of

register ‘f’ are exchanged. If ‘d’ is

‘0’, the result is placed in the W

register. If ‘d’ is ‘1’, the result is

placed in register ‘f’.

XORLW

Syntax:

Operands:

Operation:

Status Affected:

Description:

Exclusive OR literal with W

[ label ] XORLW k

0 k 255

(W) .XOR. k W)

Z

The contents of the W register

are XOR’ed with the 8-bit

literal ‘k’. The result is placed in

the W register.
