DECFSZ

Decrement f, Skip if 0

Syntax:

[ label ] DECFSZ f,d

Operands:

 f  127

 [0,1]

Operation:

(f) - 1

 (destination);

skip if result = 0

Status Affected:

None

Description:

The contents of register ‘f’ are decre-

mented. If ‘d’ is ‘0’, the result is placed

in the W register. If ‘d’ is ‘1’, the result

is placed back in register ‘f’.

If the result is ‘1’, the next instruction is

executed. If the result is ‘0’, then a

NOP

is executed instead, making it a

2-cycle instruction.

GOTO

Unconditional Branch

Syntax:

[ label ] GOTO k

Operands:

 k  2047

Operation:

 PC<10:0>

PCLATH<6:3>

 PC<14:11>

Status Affected:

None

Description:

GOTO

is an unconditional branch. The

eleven-bit immediate value is loaded

into PC bits <10:0>. The upper bits of

PC are loaded from PCLATH<4:3>.

GOTO

is a two-cycle instruction.

INCF

Increment f

Syntax:

[ label ] INCF f,d

Operands:

 f  127

 [0,1]

Operation:

(f) + 1

 (destination)

Status Affected:

Description:

The contents of register ‘f’ are incre-

mented. If ‘d’ is ‘0’, the result is placed

in the W register. If ‘d’ is ‘1’, the result

is placed back in register ‘f’.

INCFSZ

Increment f, Skip if 0

Syntax:

[ label ] INCFSZ f,d

Operands:

 f  127

 [0,1]

Operation:

(f) + 1

 (destination),

skip if result = 0

Status Affected:

None

Description:

The contents of register ‘f’ are incre-

mented. If ‘d’ is ‘0’, the result is placed

in the W register. If ‘d’ is ‘1’, the result

is placed back in register ‘f’.

If the result is ‘1’, the next instruction is

executed. If the result is ‘0’, a NOP is

executed instead, making it a 2-cycle

instruction.

IORLW

Inclusive OR literal with W

Syntax:

[ label ]

IORLW k

Operands:

 k  255

Operation:

(W) .OR. k

 (W)

Status Affected:

Description:

The contents of the W register are

OR’ed with the eight-bit literal ‘k’. The

result is placed in the W register.

IORWF

Inclusive OR W with f

Syntax:

[ label ]

IORWF

f,d

Operands:

 f  127

 [0,1]

Operation:

(W) .OR. (f)

 (destination)

Status Affected:

Description:

Inclusive OR the W register with regis-

ter ‘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’.
