ADDWF

Add W and f

Syntax:

[ label ] ADDWF f, d

Operands:

0 ≤ f ≤ 31

d ∈ [0,1]

Operation:

(W) + (f) → (dest)

Status Affected: C, DC, Z

Encoding:

0001 11df ffff

Description:

Add the contents of the W register

and 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'.

Words:

1

Cycles:

1

Example:

ADDWF TEMP_REG, 0

Before Instruction

ANDLW

AND literal with W

Syntax:

[ label ] ANDLW k

Operands:

0 ≤ k ≤ 255

Operation:

(W).AND. (k) → (W)

Status Affected: Z

Encoding:

1110 kkkk kkkk

Description:

The contents of the W register are

AND’ed with the eight-bit literal ‘k’.

The result is placed in the W

register.

Words:

1

Cycles:

1

Example:

ANDLW H'5F'

Before Instruction

W = 0xA3

After Instruction

W = 0x03

ANDWF

AND W with f

Syntax:

[ label ] ANDWF f, d

Operands:

0 ≤ f ≤ 31

d ∈ [0,1]

Operation:

(W) .AND. (f) → (dest)

Status Affected: Z

Encoding:

0001 01df ffff

Description:

The contents of the W register are

AND’ed 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’.
