IORLW

Inclusive OR literal with W

Syntax:

[ label ] IORLW k

Operands:

0  k  255

Operation:

(W) .OR. (k)  (W)

Status Affected: Z

Encoding:

Description:

1101 kkkk kkkk

The contents of the W register are

OR’ed with the eight bit literal 'k'.

The result is placed in the W regis-

ter.

IORLW 0x35

Before Instruction

W = 0x9A

After Instruction

W = 0xBF

Z =0

IORWF

Inclusive OR W with f

Syntax:

Operands:

Operation:

[ label ] IORWF f,d

0  f  31

d  [0,1]

(W).OR. (f)  (dest)

Status Affected: Z

Encoding:

0001 00df ffff

Description:

Inclusive OR the W register with

register 'f'. If 'd' is 0 the result is

placed in the W register. If 'd' is 1

the result is placed back in

register 'f'.

MOVF

Move f

Syntax:

Operands:

Operation:

[ label ] MOVF f,d

0  f  31

d  [0,1]

(f)  (dest)

Status Affected: Z

Encoding:

0010 00df ffff

Description:

The contents of register 'f' is

moved to destination 'd'. If 'd' is 0,

destination is the W register. If 'd'

is 1, the destination is file

register 'f'. 'd' is 1 is useful to test a

file register since status flag Z is

affected.

Example:

MOVF FSR, 0

After Instruction

W = value in FSR register

MOVLW

Move Literal to W

Syntax:

[ label ] MOVLW k

Operands:

0  k  255

Operation:

k  (W)

Status Affected: None

Encoding:

Description:

1100 kkkk kkkk

The eight bit literal 'k' is loaded into

the W register.
