10.2 Instruction Descriptions

ADDLW

Syntax:

Operands:

Operation:

Status Affected:

Description:

Add Literal and W

[label] ADDLW k

0  k  255

(W) + k  (W)

C, DC, Z

The contents of the W register

are added to the eight-bit literal ‘k’

and the result is placed in the W

register.

ADDWF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Add W and f

[label] ADDWF f,d

0  f  127

d 

(W) + (f)  (destination)

C, DC, Z

Add 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’.

ANDLW

Syntax:

Operands:

Operation:

Status Affected:

Description:

AND Literal with W

[label] ANDLW k

0  k  255

(W) .AND. (k)  (W)

Z

The contents of W register are

AND’ed with the eight-bit literal

‘k’. The result is placed in the W

register.

ANDWF

Syntax:

Operands:

Operation:

Status Affected:

Description:

AND W with f

[label] ANDWF f,d

0  f  127

d 

(W) .AND. (f)  (destination)

Z

AND 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’.

BCF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Bit Clear f

[label] BCF f,b

0  f  127

0b7

0  (f<b>)

None

Bit ‘b’ in register ‘f’ is cleared.

BSF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Bit Set f

[label] BSF f,b

0  f  127

0b7

1  (f<b>)

None

Bit ‘b’ in register ‘f’ is set.

BTFSS

Bit Test f, Skip if Set

Syntax:

Operands:

Operation:

Status Affected:

Description:

[label] BTFSS f,b

0  f  127

0b<7

skip if (f<b>) = 1

None

If bit ‘b’ in register ‘f’ is ‘0’, the next

instruction is executed.

If bit ‘b’ is ‘1’, then the next instruc-

tion is discarded and a NOP is

executed instead, making this a

2-cycle instruction.

BTFSC

Bit Test, Skip if Clear

Syntax:

Operands:

Operation:

Status Affected:

Description:

[label] BTFSC f,b

0  f  127

0b7

skip if (f<b>) = 0

None

If bit ‘b’ in register ‘f’ is ‘1’, the next

instruction is executed.

If bit ‘b’, in register ‘f’, is ‘0’, the

next instruction is discarded, and

a NOP is executed instead, making

this a 2-cycle instruction.
