COMF

Complement f

Syntax:

[

label ] COMF

f,d

Operands:

≤ f ≤ 127

∈ [0,1]

Operation:

(f)

→ (destination)

Status Affected:

Description:

The contents of register ’f’ are comple-

mented. If ’d’ is 0, the result is stored

in W. If ’d’ is 1, the result is stored

back in register ’f’.

DECF

Decrement f

Syntax:

[

label] DECF f,d

Operands:

≤ f ≤ 127

∈ [0,1]

Operation:

(f) - 1

→ (destination)

Status Affected:

Description:

Decrement register ’f’. If ’d’ is 0, the

result is stored in the W register. If ’d’

is 1, the result is stored back in regis-

ter ’f’

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 2TCY

instruction.

GOTO

Unconditional Branch

Syntax:

[

label ]

GOTO k

Operands:

≤ k ≤ 2047

Operation:

→ PC<10:0>

PCLATH<4:3>

→ PC<12:11>

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 2TCY

instruction
