MOVF

Move f

Syntax:

[ label ]

MOVF f,d

Operands:

≤ f ≤ 127

∈ [0,1]

Operation:

(f)

→ (destination)

Status Affected:

Description:

The contents of register f are

moved to a destination dependant

upon the status of d. If d = 0,

destination is W register. If d = 1,

the destination is file register f itself.

d = 1 is useful to test a file register,

since status flag Z is affected.

MOVLW

Move Literal to W

Syntax:

[ label ]

MOVLW k

Operands:

≤ k ≤ 255

Operation:

→ (W)

Status Affected:

None

Description:

The eight bit literal ’k’ is loaded

into W register. The don’t cares

will assemble as 0’s.

MOVWF

Move W to f

Syntax:

[ label ]

MOVWF

Operands:

≤ f ≤ 127

Operation:

(W)

→ (f)

Status Affected:

None

Description:

Move data from W register to

NOP

No Operation

Syntax:

[ label ]

NOP

Operands:

None

Operation:

No operation

Status Affected:

None

Description:

No operation.

RETFIE

Return from Interrupt

Syntax:

[ label ]

RETFIE

Operands:

None

Operation:

TOS

→ PC,

→ GIE

Status Affected:

None

RETLW

Return with Literal in W

Syntax:

[ label ]

RETLW k

Operands:

≤ k ≤ 255

Operation:

→ (W);

TOS

→ PC

Status Affected:

None

Description:

The W register is loaded with the

eight bit literal 'k'. The program

counter is loaded from the top of

the stack (the return address).

This is a two-cycle instruction.
