SUBLW

Subtract W from Literal

Syntax:

[ label ] SUBLW k

Operands:

0 ≤ k ≤ 255

Operation:

k - (W) → (W)

Status Affected: C, DC, Z

Description:

The W register is subtracted (2’s com-

plement method) from the eight bit lit-

eral 'k'. The result is placed in the W

register.

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 eight bit literal 'k'.

The result is placed in the W

register.

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'.

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 regis-

ter 'f' are exchanged. If 'd' is 0, the

result is placed in W register. If 'd' is 1,

the result is placed in register 'f'.

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'.
