Preliminary

MOVIW

Move INDFn to W

Syntax:

[ label ] MOVIW ++INDFn

[ label ] MOVIW --INDFn

[ label ] MOVIW INDFn++

[ label ] MOVIW INDFn--

[ label ] MOVIW [k]INDFn

[ label ] MOVIW INDFn

Operands:

∈ [0,1]

∈ [00, 01, 10, 11].

-32

≤ k ≤ 31

If not present, k = 0.

Operation:

INDFn

→ W

Effective address is determined by

• FSR + 1 (preincrement)

• FSR - 1 (predecrement)

• FSR + k (relative offset)

After the Move, the FSR value will be

either:

• FSR + 1 (all increments)

• FSR - 1 (all decrements)

• Unchanged

Status Affected:

Mode

Syntax

Preincrement

++INDFn

Predecrement

--INDFn

Postincrement

INDFn++

Postdecrement

INDFn--

Description:

This instruction is used to move data

between W and one of the indirect

registers (INDFn). Before/after this

move, the pointer (FSRn) is updated by

pre/post incrementing/decrementing it.

FSRn is limited to the range 0000h -

FFFFh. Incrementing/decrementing it

beyond these bounds will cause it to wrap

around.

The increment/decrement operation on

FSRn WILL NOT affect any Status bits.

MOVLB

Move literal to BSR

Syntax:

[ label ] MOVLB k

Operands:

≤ k ≤ 15

Operation:

→ BSR

Status Affected:

None

Description:

The five-bit literal ‘k’ is loaded into the

Bank Select Register (BSR).

MOVLP

Move literal to PCLATH

Syntax:

[ label ] MOVLP k

Operands:

≤ k ≤ 127

Operation:

→ PCLATH

Status Affected:

None

Description:

The seven-bit literal ‘k’ is loaded into the

PCLATH register.

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

ble as ‘0’s.

Cycles:

Example:

MOVLW

0x5A

After Instruction

0x5A

MOVWF

Move W to f

Syntax:

[ label ]

MOVWF

Operands:

≤ f ≤ 127

Operation:

(W)

→ (f)

Status Affected:

None

Description:

Move data from W register to register

‘f’.

Words:

Cycles:

Example:

MOVWF

OPTION

Before Instruction

OPTION =

0xFF

0x4F

After Instruction

OPTION =

0x4F
