MOVWI

Move W to INDFn

Syntax:

[ label ] MOVWI ++FSRn

[ label ] MOVWI --FSRn

[ label ] MOVWI FSRn++

[ label ] MOVWI FSRn--

[ label ] MOVWI k[FSRn]

Operands:

 [0,1]

 [00,01, 10, 11]

-32

 k  31

Operation:

 INDFn

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:

None

Mode

Syntax

Preincrement

++FSRn

Predecrement

--FSRn

Postincrement

FSRn++

Postdecrement

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.

The increment/decrement operation on

FSRn WILL NOT affect any Status bits.

NOP

No Operation

Syntax:

OPTION

Load OPTION_REG Register

with W

Syntax:

[ label ] OPTION

Operands:

None

Operation:

(W)

 OPTION_REG

Status Affected:

None

Description:

Move data from W register to

OPTION_REG register.

RESET

Software Reset

Syntax:

[ label ] RESET

Operands:

None

Operation:

Execute a device Reset. Resets the

nRI flag of the PCON register.

Status Affected:

None

Description:

This instruction provides a way to

execute a hardware Reset by soft-

ware.
