MOVIW

Syntax:

Operands:

Operation:

Status Affected:

Move INDFn to W

[ label ] MOVIW ++FSRn

[ label ] MOVIW --FSRn

[ label ] MOVIW FSRn++

[ label ] MOVIW FSRn--

[ label ] MOVIW k[FSRn]

n  [0,1]

-32  k  31

If not present, k = 0.

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

Syntax

++FSRn

--FSRn

FSRn++

FSRn--

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.

Note: The INDFn registers are not

physical registers. Any instruction that

accesses an INDFn register actually

accesses the register at the address

specified by the FSRn.

FSRn is limited to the range 0000h -

FFFFh. Incrementing/decrementing it

beyond these bounds will cause it to

wrap-around.

MOVLB

Syntax:

Operands:

Operation:

Status Affected:

Description:

Move literal to BSR

[ label ] MOVLB k

0  k  15

k  BSR

None

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

Bank Select Register (BSR).

MOVLP

Syntax:

Operands:

Operation:

Status Affected:

Description:

Move literal to PCLATH

[ label ] MOVLP k

0  k  127

k  PCLATH

None

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

PCLATH register.

MOVLW

Syntax:

Operands:

Operation:

Status Affected:

Description:

Words:

Cycles:

Example:

Move literal to W

[ label ] MOVLW k

0  k  255

k  (W)

None

The eight-bit literal ‘k’ is loaded into W

register. The “don’t cares” will assem-

ble as ‘0’s.

Example:

Move W to f

[ label ] MOVWF f

0  f  127

(W)  (f)

None

Move data from W register to register

‘f’.
